MATERIAL COMPATIBILITY
Find the Right Finish for Your Material
These are starting points for review, not a universal compatibility guarantee.
| Your base material | Options to review | Confirm for your part |
|---|---|---|
| Aluminum | Anodizing · conversion coating · powder coating | Alloy, silicon content, coating build-up and appearance |
| Stainless steel | Passivation · brushing · polishing | Grade, contamination, grain direction and cosmetic zones |
| Carbon steel | Zinc plating · powder coating · black oxide | Corrosion system, steel strength and protected interfaces |
| Brass / copper | Suitable plating · polishing · protective coating | Deposit specification, tarnish and electrical requirements |
| Zinc die cast | Suitable plating · painting · powder coating | Porosity, preparation, curing conditions and finish sample |
| Plastics | Compatible painting · printing · marking | Polymer, adhesion, temperature limits and artwork |
Alloy, heat treatment, surface condition and the finish specification affect feasibility. Review high-silicon die-cast aluminum before specifying cosmetic anodizing.
DFM & MASKING BEFORE FINISHING
Design It Right for Your Finished Fit
Put functional surfaces and cosmetic expectations on the same drawing.
- Masking: mark contact pads, seal faces and protected features.
- Threads & holes: specify the required finished condition.
- Coating build-up: review allowance on tight fits and mating parts.
- Edges & welds: agree preparation and permissible witness marks.
- Cosmetic zones: identify visible surfaces and inspection conditions.
- Racking points: agree acceptable fixture-contact locations.
COMPARE FINISHES AROUND YOUR REQUIREMENTS
Make Your Tradeoffs Before Production
A finish can improve one requirement while changing another. Review the complete system.
| Finish family | Your main review | Dimensional / assembly consideration | Appearance decision |
|---|---|---|---|
| Anodizing | Aluminum protection and specified wear performance | Growth and penetration affect finished fits; review masking | Alloy, pretreatment, color and sealing |
| Powder coating | Protective coating and cosmetic finish | Build-up and curing conditions; mask functional interfaces | Texture, gloss and approved color reference |
| Electroless nickel | Specified deposit performance | Deposit thickness on bores, threads and mating faces | Substrate marks and preparation |
| Zinc plating | Corrosion-protection system for suitable steel | Deposit and post-treatment requirements | Passivate appearance and allowable variation |
| Conversion coating | Corrosion protection, paint base or electrical requirements | Specify class and contact requirements | Alloy-dependent shade and permitted marks |
| Black oxide | Dark appearance and supplementary protection | Review material and post-treatment | Surface preparation and oiled appearance |
FROM YOUR DRAWING TO AN APPROVED FINISH
Agree the Sample. Define the Acceptance.
A color code alone does not define texture, gloss or allowable variation.
- Confirm your finish specification and drawing revision.
- Review a representative color and texture sample.
- Agree limit samples for visible surfaces where needed.
- Approve the first article against functional and cosmetic criteria.
- Control the finish and revision for repeat production.
- Define batch checks, packaging and required records.

Frequently Asked Questions
Which surface finish should I choose for my part?
Start with your substrate, operating environment, wear, electrical contact and appearance requirements. Share the drawing and specifications so the finish can be reviewed with masking, dimensions and inspection.
Will finishing change my dimensions or tolerances?
Coatings and treatments can affect finished dimensions. Mark critical bores, threads, seal faces and fits. Agree machining allowance, masking and the required inspection condition before production.
Can you match a specific color and texture?
Provide the color reference, gloss, texture and cosmetic zones. Approve a representative sample and agree acceptable variation. Material and pretreatment can affect appearance, especially with anodizing.
Can you mask electrical contacts and threads?
Identify the areas and required finished condition on your drawing. Review the masking boundary, contact requirements and inspection method as part of the finish plan.
What affects cost and lead time?
Material, part geometry, quantity, preparation, masking, coating system, sample approval and inspection all influence the quote. Include your target date, batch demand and delivery destination.
