Surface Finishes for Aluminum Motor Components
A buyer-focused guide to anodizing, passivation, polishing and finish callouts for precision-machined components.
Match the finish to the application
Anodizing can improve corrosion resistance, wear performance and appearance, but coating thickness and masking requirements must be considered at tight interfaces. Define cosmetic zones separately from functional surfaces.
Specify what can be inspected
State finish type, color range, thickness, protected threads, contact points and acceptable appearance standards. Approved samples are especially useful for repeat cosmetic requirements.
