Anodized Aluminum Parts – Manufacturers and Factory China

Product Details: Anodized aluminum parts are produced through an electrochemical process known as anodizing. This process involves submerging the aluminum part in an acid electrolyte bath and passing an electrical current through it, resulting in the formation of a thick, porous layer of aluminum oxide on the surface. The anodizing process can be categorized into several types, including Type I (Chromic Acid Anodizing), Type II (Sulfuric Acid Anodizing), and Type III (Hard Anodizing). Each type has specific applications and standards, such as MIL-A-8625 and ASTM B580. The coating thickness varies by type, with Type III producing the thickest coatings for high wear

and corrosion resistance[1][3][5].
