Type II Sulfuric Anodization

MIL-A-8625, Type II

Anodization is a type of electrolytic passivation. In other words, aluminum parts are placed in a sulfuric acid solution and an electric current is applied. This process creates an outer shield of aluminum oxide to protect parts from corrosion and wear. This is a great way to treat and color aluminum and a popular choice for our customers. Anodized aluminum parts can be dyed almost any color. Peak Finishing delivers the best sulfuric anodizing in Utah—and we get it done on time.
