Bead blast + Anodized color

Anodizing creates a corrosion-resistant finish. Parts can be anodized in different colors—clear, black, red, and gold are most common—and is usually associated with aluminum. And with bead blast, the part surface is left with a smooth, matte appearance.(Note: 1.There will be a certain color difference between the actual color after anodizing and the above color board. 2.Rack marks are inherent to the anodizing process. When engineering a part that will be anodized, you'd better identify where the part will be racked. Typically, the racking location is chosen to minimize the visibility of the mark after the part is assembled.)
