Chromate Conversion Coating of Aluminum

Chromate conversion coating converts the surface properties of aluminum.  Chromate provides excellent corrosion resistance, is conductive and results in no measureable buildup on the parts.  Chromate is the most common coating for corrosion protection of aluminum.  It is commonly used for an undercoat for paint or adhesive applications due to the excellent bonding properties it provides.
