Explore 11 process guides covering protective, functional, cosmetic, thermal, and identification finishes selected around your material, performance requirements, and desired appearance.

Project guide

Which finish suits the material and function?

Compare finishes by substrate, intended function and appearance. Include dimensional effects, masking and testing in the decision rather than choosing by color alone.

Review acceptance and handover requirements

Decision guide

Anodizing or powder coating: decide from the requirement

For an aluminum component, anodizing and powder coating can both be candidates, but their process and acceptance requirements differ. The preferred route depends on function, appearance, geometry and the specified coating system.

Review points for your project
Selection factorAnodizing reviewPowder coating review
SubstrateConfirm the aluminum alloy and its suitability for the specified anodizing processConfirm substrate preparation and compatibility with the powder and cure schedule
AppearanceAlloy and surface preparation influence the result; define a color or appearance referenceDefine color, gloss, texture and which surfaces are cosmetic
Fits and protected areasSpecify the anodizing type, thickness and final dimensional requirementsAllow for the specified coating build; define threads, contacts and surfaces to mask
Service conditionsMatch the specified treatment and acceptance tests to the applicationMatch the coating system and required tests to the environment

What does a complete surface-finishing specification include?

Define the substrate, finish system, protected areas, final dimensional requirements and acceptance method. Agree appearance references and any performance tests instead of relying on a process or color name alone.

Scroll horizontally to compare all columns.

Requirements to agree for the actual order
RequirementMark on the drawing or orderConfirm before processing
A fit must remain usable after finishingFinal dimensions, threads, contact faces and masking boundariesAgree which dimensions apply after treatment and how they will be checked
Visible parts need a consistent appearanceCosmetic zones, color, gloss or texture reference and viewing conditionsAgree the reference and acceptance criteria; images on this site are not approved finish samples
Corrosion or wear performance mattersApplicable specification, environment and required test methodConfirm the coating system and test scope; a process label does not prove a service life
Records are needed with shipmentRequired finish documents, part identification and traceability levelConfirm document availability and any external processing or test responsibility in the quote

Finishing can affect dimensions and appearance. Resolve conflicts between finish requirements and functional interfaces before approving the route.

Neither process is a universal replacement for the other. Specify the actual finish and acceptance method, and confirm final dimensions rather than choosing from color alone.
