Alloy choice
6061 is widely used for general machined parts; 7075 may suit higher-strength applications. Final selection should follow the drawing and use conditions.
Finish planning
Machined finish, bead blasting, anodizing, and hard anodizing create different appearance and wear characteristics.
Cosmetic control
Visible faces, color references, plug or masking requirements, and acceptable handling marks should be stated before quotation.

Buyer Questions
Should the alloy be written on the drawing?
Yes. The exact grade and temper help the supplier quote material and machining consistently.
What finish information is useful?
Specify finish type, color, gloss or texture, cosmetic faces, threaded holes, and any masking requirement.
