Chromic Acid Anodizing
Chromic acid anodizing, or type 1 anodizing, enhances the corrosion resistance of aluminum parts and produces a thin opaque film that is soft, ductile, non-conductive, and to a degree, self-healing. A typical thickness is usually 0.00005-0.0001 inches. Chromic anodize may be applied as a pretreatment before painting to enhance adhesion, and it is harder to dye than sulfuric acid (type 2) anodize. The big advantage of the chromic acid anodizing process over other anodizing processes is that it does not lower the fatigue strength of the aluminum or damage the base material if it is entrapped in lap joints or blind holes. After the chromic acid anodizing process, the solution may be sealed in either hot water or sodium dichromate solutions.

Why Choose Chromic Anodizing Services?
More corrosion and fatigue resistant than sulfuric acid anodizing, chromic acid anodizing offers a solution that’s flexible and durable for industries that require more specific treatment than that offered by sulfuric or hardcoat anodizing. Chromic anodize produces a very thin layer of coating that is strong yet pliant, making it a perfect solution for products that demand a little more flex. Type 1 anodize is commonly used in aerospace and defense in aluminum parts that must respond to great amounts of pressure. The thinner the coat, the more fatigue resistance, which makes type 1 anodizing a great fit for products that depend on both ultimate durability and flexibility.
