Anodizing is the process that makes a non-ferrous metal, such as aluminum, corrosion-resistant and non-conductive. The process can also be used to color a part. Some anodized parts have a hardness equal to the strongest of steels and iron. Anodized parts have longer life and typically don’t chip. The oxide surface will not decompose and cause health concerns.<\/p>\n

Anodizing protects aircraft components from corrosion and from undesired electric currents. Since anodized parts can withstand high heat, anodizing is also a preferred process of the food service industry.<\/p>\n

Cleaned parts are submerged into an electrolyte solution that is set to the right temperature. A current is applied to the parts that creates a strong oxide layer on the surface of the part. After an optional color is applied, the process ends with a nickel acetate, sodium dichromate, teflon, or hot water seal to secure the corrosion resistance and color stability.<\/p>\n

According to MIL-A-8625, there are three main types of anodizing:<\/p>\n

\n
1. Type I – Chromic. Choose this option if you want the anodic layer to be very thin (.00002-.0001). The layer is too thin to successfully add color. (FMC does not process Type I at this time)<\/li>\n
2. Type II – Sulfuric. Choose this option for moderate thickness (.0001-.001) and for coloring the parts.<\/li>\n
3. Type III – Hard Sulfuric. Choose this option if you want the part to have a thicker (.001-.002)and more abrasion-resistant coating.<\/li>\n<\/ol>\n
