Anodizing is an electrochemical passivation process that beneficially alters the microscopic texture of metal, and becomes integral to it.  Anodizing increases the oxide layer, imparting a highly durable, corrosion-and-wear resistant, anodic oxide finish with excellent adhesion properties. Anodizing is primarily used on aluminum, although other nonferrous materials, including magnesium, niobium, zirconium and titanium, also can be anodized.

There are 10 types of anodizing. The most prevalent are Type I “CAA” chromic acid; Type II “SAA” sulfuric acid; Type III “HCA”, hardcoat or modified hardcoat; “PAA” phosphoric acid, “BSAA” boric and sulfuric acid, and “TFSAA” thin film sulfuric acid anodizing.

Tri-Mer has the expertise, resources and capacity to design, manufacture and commission anodizing systems of all types, as well as electroplating and other metal finishing systems.
