Black Oxide: Black oxide is a conversion coating that is used for appearance and to add mild corrosion resistance to minimize light reflection. It is used for ferrous materials and is impregnated using oil to achieve maximum corrosion resistance. It provides a matte deep black appearance, which is available in rack or barrel. Black Oxide Black Oxide is a conversion coating, changing the surface of the steel to black while maintaining the dimensional integrity of the part. It is used extensively on fasteners, tools, gages, hardware, automotive and furniture components along with many other applications.

Black Oxide: The Black Oxide process causes virtually no dimensional change to the part, which does occur with painting or zinc plating; making black oxide appealing in instances where a coating is required with no “build-up” of material.

There are two classes of coating: Class I-A. This is a thick coating for use as a final finish or pre-treatment to paint or powder coating. This is gold, brown or yellow depending on coating weight and alloy. Also provides maximum protection against corrosion, painted or unpainted. Class III. This is a thin coating for low contact resistance. Aug 04, 2018 · The trick is finding a coating that fits your lifestyle and personal tastes. Gun Bluing.
