The aluminum bracket that corrodes because it was not anodized. The steel shaft that rusts in storage because it arrived as-machined. The cosmetic enclosure that looks cheap because the powder coat is uneven. <strong>Surface finishing<\/strong> is not the last 5% of the job \u2014 it is what determines whether the part survives in its operating environment. This guide covers the eight most common surface finishes for CNC machined and sheet metal parts, with practical selection guidance for procurement engineers and hardware buyers.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table style=\"width:100%;border-collapse:collapse;margin:15px 0\"><thead><tr style=\"background:#004c97;color:#fff\"><th>Surface Finish Quick Selector<\/th><th>Best For<\/th><th>Materials<\/th><th>Thickness<\/th><th>Cost<\/th><th>Lead Time<\/th><\/tr><\/thead><tbody><tr style=\"border-bottom:1px solid #e5e5e5\"><td><strong>Anodize Type II<\/strong><\/td><td>Corrosion + color on aluminum<\/td><td>Aluminum only<\/td><td>5\u201315 \u00b5m<\/td><td>$$<\/td><td>+3\u20135 days<\/td><\/tr><tr style=\"border-bottom:1px solid #e5e5e5\"><td><strong>Anodize Type III<\/strong><\/td><td>Wear resistance on aluminum<\/td><td>Aluminum only<\/td><td>25\u201350 \u00b5m<\/td><td>$$$<\/td><td>+5\u20137 days<\/td><\/tr><tr style=\"border-bottom:1px solid #e5e5e5\"><td><strong>Powder Coating<\/strong><\/td><td>Durable color on steel\/aluminum<\/td><td>Steel, aluminum<\/td><td>50\u2013150 \u00b5m<\/td><td>$$<\/td><td>+3\u20135 days<\/td><\/tr><tr style=\"border-bottom:1px solid #e5e5e5\"><td><strong>Passivation<\/strong><\/td><td>Stainless corrosion restoration<\/td><td>Stainless steel<\/td><td>0 (chemical)<\/td><td>$<\/td><td>+1 day<\/td><\/tr><tr style=\"border-bottom:1px solid #e5e5e5\"><td><strong>Electroless Nickel<\/strong><\/td><td>Uniform corrosion on steel<\/td><td>Steel, aluminum<\/td><td>5\u201325 \u00b5m<\/td><td>$$<\/td><td>+3\u20135 days<\/td><\/tr><tr style=\"border-bottom:1px solid #e5e5e5\"><td><strong>Zinc Plating<\/strong><\/td><td>Low-cost steel corrosion<\/td><td>Steel<\/td><td>5\u201315 \u00b5m<\/td><td>$<\/td><td>+2\u20133 days<\/td><\/tr><tr style=\"border-bottom:1px solid #e5e5e5\"><td><strong>Bead Blast<\/strong><\/td><td>Uniform matte cosmetic<\/td><td>Any metal<\/td><td>0 (surface texture)<\/td><td>$<\/td><td>+1 day<\/td><\/tr><tr style=\"border-bottom:1px solid #e5e5e5\"><td><strong>Black Oxide<\/strong><\/td><td>Mild steel cosmetic + light corrosion<\/td><td>Steel<\/td><td><1 \u00b5m<\/td><td>$<\/td><td>+2\u20133 days<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Anodizing: The Aluminum Workhorse<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Anodizing<\/strong> is an electrochemical process that grows a controlled oxide layer on the surface of aluminum. Unlike a coating that sits on top of the metal, anodizing <strong>converts the aluminum surface itself<\/strong> into aluminum oxide \u2014 it becomes part of the part. This gives anodizing two unique properties: it cannot peel or chip, and it preserves the underlying dimensional accuracy because the oxide grows both outward and inward from the original surface.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Type II (Decorative\/Architectural)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Type II anodizing produces a 5\u201315 \u00b5m oxide layer. It accepts dye well, making it the go-to finish for <strong>colored aluminum parts<\/strong> \u2014 consumer electronics housings, architectural trim, nameplates. Clear (natural) Type II is the most common specification for general corrosion protection. Black Type II is standard for optical and aesthetic parts. The oxide layer is hard enough for light handling but will scratch under abrasion.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Cost:<\/strong> $3\u20138 per medium-sized part (batch pricing). <strong>Limitations:<\/strong> Only 6000 and 7000 series aluminum anodize well. High-copper alloys (2000 series) turn dark and blotchy. Cast aluminum anodizes poorly due to silicon content. Welded areas anodize differently than base metal \u2014 visible color variation is normal and expected.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Type III (Hardcoat)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Type III hardcoat anodizing produces a 25\u201350 \u00b5m oxide layer \u2014 thick enough to provide genuine <strong>wear resistance<\/strong>. The surface hardness reaches 50\u201370 HRC, comparable to case-hardened steel. It is used on aluminum parts that see sliding contact, abrasion, or frequent assembly\/disassembly: pistons, valve bodies, linear bearing housings, firearm components. The thicker layer does affect dimensions: a 50 \u00b5m hardcoat adds ~25 \u00b5m to external surfaces and reduces internal bores by ~25 \u00b5m. If you have a tight-tolerance bore, specify &#8220;mask bore before hardcoat&#8221; or &#8220;hone after hardcoat&#8221; \u2014 the shop needs to know before they process the part.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Cost:<\/strong> $8\u201320 per part. <strong>Color limitation:<\/strong> Type III naturally produces a dark gray-green color. It accepts black dye reasonably well. Bright colors (red, blue, yellow) are not achievable with Type III.<\/p>\n\n\n\n<p class=\"has-background wp-block-paragraph\" style=\"background-color:#f8f9fb;padding-top:10px;padding-right:14px;padding-bottom:10px;padding-left:14px\"><strong>Best for anodizing:<\/strong> 6061-T6 aluminum parts needing corrosion protection (Type II, clear) or wear surfaces (Type III, hardcoat).<br><strong>Avoid when:<\/strong> Your part has press-fit tolerances tighter than 0.01 mm and you cannot mask or post-machine the bore \u2014 the anodize thickness will close the tolerance.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Powder Coating: The Toughest Color Finish<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Powder coating<\/strong> applies a dry thermoplastic or thermoset powder to the part electrostatically, then cures it in an oven at 180\u2013200\u00b0C. The powder melts and flows into a continuous film that is <strong>chemically bonded<\/strong> to the surface. The result is a finish that resists chipping, scratching, and UV fading far better than wet paint \u2014 and with zero VOC emissions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Powder coating is the dominant finish for <strong>sheet metal enclosures, brackets, chassis, and welded assemblies<\/strong>. It offers the widest color range of any metal finish \u2014 RAL and Pantone color matching is standard. Surface textures range from high-gloss to matte to fine-texture (&#8220;sandtex&#8221;) that hides fingerprints and minor surface imperfections.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Key design consideration:<\/strong> Powder coating adds 50\u2013150 \u00b5m to every coated surface. Threaded holes will close up unless plugged before coating. Press-fit bores will go out of tolerance. Masking (plugs, tape, silicone caps) is standard practice but adds cost per masked feature. For parts with many threaded holes, factor $0.50\u20131.00 per masked hole into your finishing budget.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Cost:<\/strong> $5\u201315 per medium-sized part. <strong>Batch minimums:<\/strong> Most coating shops have a minimum lot charge ($80\u2013150) regardless of part quantity. One bracket costs the same as 20 brackets until you exceed the minimum.<\/p>\n\n\n\n<p class=\"has-background wp-block-paragraph\" style=\"background-color:#f8f9fb;padding-top:10px;padding-right:14px;padding-bottom:10px;padding-left:14px\"><strong>Best for powder coating:<\/strong> Steel and aluminum enclosures, panels, and brackets that need a durable colored finish with impact resistance.<br><strong>Avoid when:<\/strong> Your part has tight-tolerance bores that cannot be masked, or operating temperatures exceed 200\u00b0C \u2014 the coating will soften.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Anodizing vs Powder Coating: How to Choose<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This is the most common finishing decision for aluminum parts. Here is the head-to-head comparison:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table style=\"width:100%;border-collapse:collapse;margin:15px 0\"><thead><tr style=\"background:#004c97;color:#fff\"><th>Decision Factor<\/th><th>Anodizing (Type II)<\/th><th>Powder Coating<\/th><\/tr><\/thead><tbody><tr style=\"border-bottom:1px solid #e5e5e5\"><td><strong>Dimensional impact<\/strong><\/td><td>Minimal (5\u201315 \u00b5m, partly inward growth)<\/td><td>Significant (50\u2013150 \u00b5m added to all surfaces)<\/td><\/tr><tr style=\"border-bottom:1px solid #e5e5e5\"><td><strong>Wear resistance<\/strong><\/td><td>Moderate (Type II) to high (Type III)<\/td><td>Low \u2014 coating scratches under abrasion<\/td><\/tr><tr style=\"border-bottom:1px solid #e5e5e5\"><td><strong>Impact resistance<\/strong><\/td><td>Poor \u2014 oxide layer is brittle<\/td><td>Excellent \u2014 coating absorbs impact<\/td><\/tr><tr style=\"border-bottom:1px solid #e5e5e5\"><td><strong>Color range<\/strong><\/td><td>Limited (clear, black, gold, few colors)<\/td><td>Unlimited (RAL, Pantone matching)<\/td><\/tr><tr style=\"border-bottom:1px solid #e5e5e5\"><td><strong>UV resistance<\/strong><\/td><td>Excellent \u2014 oxide does not degrade<\/td><td>Good \u2014 modern powders resist fading<\/td><\/tr><tr style=\"border-bottom:1px solid #e5e5e5\"><td><strong>Corrosion protection<\/strong><\/td><td>Excellent (salt spray 200\u2013400 hrs)<\/td><td>Excellent (salt spray 500\u20131,000 hrs)<\/td><\/tr><tr style=\"border-bottom:1px solid #e5e5e5\"><td><strong>Can it chip?<\/strong><\/td><td>No \u2014 part of the metal<\/td><td>Yes \u2014 coating sits on top<\/td><\/tr><tr style=\"border-bottom:1px solid #e5e5e5\"><td><strong>Threaded holes<\/strong><\/td><td>No masking needed (thin)<\/td><td>Must mask or chase threads after<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Rule of thumb:<\/strong> If the part has tight tolerances, threaded holes, or sliding surfaces \u2192 <strong>anodize<\/strong>. If the part is a cosmetic enclosure that needs a specific color and impact resistance \u2192 <strong>powder coat<\/strong>. If you need both precision and color, anodize then paint \u2014 but this is expensive and rarely necessary.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Passivation: Mandatory for Stainless Steel<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">When stainless steel is machined, microscopic particles of free iron from the cutting tool embed in the surface. These iron particles rust \u2014 even on &#8220;stainless&#8221; steel. <strong>Passivation<\/strong> is a chemical treatment (typically nitric or citric acid) that dissolves the surface iron and allows the natural chromium oxide layer to reform undisturbed. It does not change the part&#8217;s appearance, dimensions, or surface roughness. It simply makes stainless steel actually stainless.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>When to specify:<\/strong> Always. On every stainless part. There is no downside. The cost is negligible ($1\u20133\/part), the lead time impact is 1 day, and the alternative \u2014 rusty &#8220;stainless&#8221; parts arriving at your customer \u2014 is far more expensive. Specify per ASTM A967 or AMS 2700.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Electroless Nickel Plating: Uniform Protection for Steel<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Electroless nickel<\/strong> deposits a nickel-phosphorus alloy onto the part surface through a chemical reaction \u2014 no electric current required. Unlike electroplating, which deposits thicker layers on external corners and thinner layers in recesses, electroless nickel deposits <strong>perfectly uniformly<\/strong> on every surface, inside and out. This makes it the finish of choice for parts with complex internal geometry: manifolds, valve bodies, pump housings.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Key properties:<\/strong> Excellent corrosion resistance (salt spray 100\u20131,000 hrs depending on thickness), moderate hardness (45\u201350 HRC as-plated, up to 65 HRC with heat treatment), and good lubricity for sliding parts. Available in mid-phosphorus (6\u20139% P, general purpose) and high-phosphorus (10\u201313% P, superior corrosion for marine\/chemical environments).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Cost:<\/strong> $8\u201325 per part. <strong>Thickness:<\/strong> Typically specified at 5\u201325 \u00b5m. Can be built up to 75 \u00b5m for corrosion-intensive applications.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Zinc Plating, Black Oxide, and Bead Blast: The Budget Options<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Zinc plating<\/strong> is the lowest-cost corrosion protection for steel \u2014 $1\u20133 per part, 2\u20133 day lead time. The characteristic silver or yellow (yellow chromate) finish provides moderate corrosion resistance (salt spray 72\u2013200 hrs). Standard for fasteners, brackets, and hardware that will not be visible. Not suitable for cosmetic surfaces \u2014 zinc plating produces a slightly uneven, industrial appearance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Black oxide<\/strong> is a chemical conversion coating that turns steel a deep black color \u2014 purely cosmetic with very light corrosion protection (needs oil to prevent rust). Used on tooling, firearm components, and decorative hardware where the black color is the primary requirement and the part will be regularly oiled. Cost: $1\u20133\/part. Cannot be used outdoors without supplemental protection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Bead blasting<\/strong> is not a coating \u2014 it is a mechanical surface treatment that propels glass beads at high pressure to create a <strong>uniform matte texture<\/strong>. It removes machining marks and gives the part a consistent, professional appearance. Often used as a pre-treatment before anodizing or powder coating to improve adhesion, or as a standalone cosmetic finish on stainless steel and aluminum parts \u2014 especially for parts that will be <a href=\"https:\/\/bravofabs.com\/sheet-metal-fabrication-services\/\">laser cut or welded<\/a> where heat discoloration needs to be blended. Cost: $2\u20135\/part. No dimensional change. No corrosion protection.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Surface Finish Selection Decision Tree<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Use this structured decision tree to select the right finish for your part:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>What is the material?<\/strong> If stainless steel \u2192 <strong>passivate<\/strong> (always) + optional bead blast for cosmetic. If aluminum \u2192 go to step 2. If mild steel \u2192 go to step 3.<\/li>\n<li><strong>Does the aluminum part need wear resistance?<\/strong> Yes \u2192 <strong>Type III hardcoat anodize<\/strong>. No, but needs corrosion protection + color \u2192 <strong>Type II anodize<\/strong>. No, but needs impact-resistant color \u2192 <strong>powder coat<\/strong>.<\/li>\n<li><strong>Is the steel part cosmetic (visible surface)?<\/strong> Yes and needs durable color \u2192 <strong>powder coat<\/strong>. Yes but only needs matte uniformity \u2192 <strong>bead blast + clear coat<\/strong> or <strong>black oxide<\/strong>. No (internal\/hidden) \u2192 <strong>zinc plate<\/strong> for lowest cost.<\/li>\n<li><strong>Does the part have complex internal geometry?<\/strong> Yes and needs uniform corrosion protection \u2192 <strong>electroless nickel<\/strong>. The chemical deposition reaches where electroplating cannot.<\/li>\n<li><strong>Is cost the overriding factor?<\/strong> \u2192 <strong>zinc plate<\/strong> (steel) or <strong>as-machined<\/strong> (aluminum, if environment allows). Not every part needs a finish \u2014 but every part needs a deliberate decision about it.<\/li>\n<\/ol>\n\n\n\n<p class=\"has-background wp-block-paragraph\" style=\"background-color:#f8f9fb;padding-top:10px;padding-right:14px;padding-bottom:10px;padding-left:14px\"><strong>Real case:<\/strong> A German industrial equipment manufacturer ordered 200 aluminum sensor housings with a tight \u00b10.02 mm bore. The initial order specified powder coating. After masking 200 bores ($400 extra) and chasing threads post-coating, the per-part finishing cost was $18. On the re-order, they switched to Type II clear anodize: no masking needed, no thread chasing, finishing cost dropped to $5\/part. The $2,600 savings on 200 parts came from choosing the right finish \u2014 not from negotiating price.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion: Specify the Finish Your Part Needs \u2014 Not the One You Know<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Most engineers default to the <strong>surface finish<\/strong> they used on the last project. Anodize. Powder coat. Whatever the drawing template had. But the right finish depends on material, environment, tolerance requirements, and budget \u2014 and the wrong one costs more than just money. It costs time in masking, rework from tolerance interference, and corrosion failures in the field. Spend five minutes with the decision tree above. The finish you need might not be the finish you assumed. And that five minutes might save you $2,600 on your next order.<\/p>\n\n<div class=\"wp-block-group is-layout-constrained wp-container-core-group-is-layout-cbfb3306 wp-block-group-is-layout-constrained\" style=\"border-left-color:#2563eb;border-left-width:4px;border-left-style:solid;background-color:#f0f4ff;margin-top:32px;margin-bottom:0;padding-top:12px;padding-bottom:12px;padding-left:20px;padding-right:24px\">\n\n\n<h4 class=\"wp-block-heading\" style=\"font-size:15px;font-style:normal;font-weight:700;line-height:1.4;margin-top:0;margin-bottom:8px\">\ud83d\udd17 Related Manufacturing Services &amp; Articles<\/h4>\n\n\n\n<ul class=\"wp-block-list\" style=\"font-size:14px;line-height:1.7;padding-left:18px\">\n<li><strong><a href=\"https:\/\/bravofabs.com\/cnc-machining-service\/\">CNC Machining Service<\/a><\/strong> \u2014 precision milling &amp; turning with integrated finishing under one roof<\/li>\n<li><strong><a href=\"https:\/\/bravofabs.com\/sheet-metal-fabrication-services\/\">Sheet Metal Fabrication<\/a><\/strong> \u2014 laser cutting, bending, welding &amp; powder coating for complete assemblies<\/li>\n<li><strong><a href=\"https:\/\/bravofabs.com\/cnc-machining-parts-complete-guide\/\">CNC Machining Parts: Complete Guide<\/a><\/strong> \u2014 materials, tolerances, and surface finishes covered in depth<\/li>\n<li><strong><a href=\"https:\/\/bravofabs.com\/how-much-does-cnc-machining-cost\/\">How Much Does CNC Machining Cost?<\/a><\/strong> \u2014 finish cost breakdown: anodizing, powder coat, plating pricing<\/li>\n<li><strong><a href=\"https:\/\/bravofabs.com\/cnc-machining-aluminum\/\">CNC Machining Aluminum: Grades, Speeds &amp; Surface Finish<\/a><\/strong> \u2014 deep dive on aluminum-specific finishing (anodizing, chromate conversion)<\/li>\n<\/ul>\n\n\n<\/div>\n\n\n\n<div class=\"wp-block-group has-background is-layout-constrained wp-container-core-group-is-layout-e86b207e wp-block-group-is-layout-constrained\" style=\"border-color:#1e73be33;border-width:2px;border-radius:8px;background-color:#f0f7ff;padding-top:20px;padding-right:24px;padding-bottom:20px;padding-left:24px\">\n<h3 class=\"wp-block-heading\">Free Download: Surface Finishing Quick Reference<\/h3>\n<p class=\"wp-block-paragraph\">Two-page reference: anodizing vs powder coating side by side, which to specify, and the pre-finish checklist (masking, roughness, colour reference).<\/p>\n<div id=\"bf-lead-form-wrap\" style=\"margin-top:16px\">\n  <button id=\"bf-lead-btn\" onclick=\"document.getElementById('bf-lead-form').style.display='block';this.style.display='none'\" style=\"display:inline-block;background:#0693e3;color:#fff;padding:10px 24px;border:none;border-radius:6px;font-size:15px;font-weight:600;cursor:pointer\">Download Free PDF \u2192<\/button>\n  <form id=\"bf-lead-form\" method=\"post\" action=\"\" style=\"display:none;margin-top:16px;padding:16px;background:#fff;border-radius:8px;border:1px solid #d1d5db\">\n    <input type=\"hidden\" name=\"bf_lead_magnet\" value=\"surface_finishing\">\n    <div style=\"margin-bottom:12px\"><input type=\"text\" name=\"name\" placeholder=\"Your Name *\" required style=\"width:100%;padding:8px 12px;border:1px solid #d1d5db;border-radius:4px;font-size:14px\"><\/div>\n    <div style=\"margin-bottom:12px\"><input type=\"email\" name=\"email\" placeholder=\"Work Email *\" required style=\"width:100%;padding:8px 12px;border:1px solid #d1d5db;border-radius:4px;font-size:14px\"><\/div>\n    <div style=\"margin-bottom:16px\"><input type=\"text\" name=\"company\" placeholder=\"Company (optional)\" style=\"width:100%;padding:8px 12px;border:1px solid #d1d5db;border-radius:4px;font-size:14px\"><\/div>\n    <button type=\"submit\" style=\"display:inline-block;background:#0693e3;color:#fff;padding:10px 24px;border:none;border-radius:6px;font-size:15px;font-weight:600;cursor:pointer\">Get PDF &amp; Download \u2192<\/button>\n  <\/form>\n<\/div>\n<\/div>\n\n\n<div class=\"wp-block-group has-light-gray-background-color has-background is-layout-constrained wp-container-core-group-is-layout-e86b207e wp-block-group-is-layout-constrained\" style=\"border-color:#1e73be;border-width:2px;padding-top:20px;padding-right:24px;padding-bottom:20px;padding-left:24px\">\n\n\n<h3 class=\"wp-block-heading\">Need Surface Finishing for Your CNC Parts?
