Chromate conversion coating is a type of conversion coating used to passivate aluminum alloys (i.e. to make inactive or less reactive). It is primarily used as a corrosion inhibitor, primer or to retain electrical conductivity. Used in many different fields, we use the Tri-Vallent version. This Tri-Vallent is widely accepted in the electronics, aerospace, marine and military fields because of its health benefits. Our standard is the Mil-C-5541 type II, class 1A and Class 3.
