Parkerizing is a method used on ferrous metals to create additional protection from corrosion. There are a number of ferrous metals suitable for parkerizing which include wrought iron, cast iron, steel and alloy steel;  the process is not suitable for non-ferrous metals like a copper, brass, aluminium, and plastic items. The process uses multiple batching tanks; to clean the surface, apply the solution and extend the wear properties. Parkerizing is commonly associated with automobiles parts, firearms, and aircraft.

​

The Parkerizing technique is a Phosphate etching process that produces a hard Matte or Dull finish that is actually etched into the surface of the metal, it is both very Durable and Anti Reflective and with excellent oil holding properties.

​

Parkerizing is much easier to use than bluing because as it is a Matte Finish the parts or items you want to Parkerize do not have to be polished, they can be acid dipped, sanded, bead blasted or sand blasted.  In fact a lot of nicks and scratches that would show up on a blued item would not even be seen after Parkerizing.

​

It can also be used to improve the wear resistance of materials by adding a surface coating. In the commercial world this process is used to improve the surface roughness, corrosion resistance, wear resistance and protection from indentation and scratches. The process is also known by a number of alternative names such as: Phosphating, Phosphatizing, Bonderizing & Phosphate coating

War Eagle Labs uses Manganese in the Parkerizing process and can acheive Dark Gray and Black coatings.
