Black Oxide

Black Oxide is used to provide a protective over metal. It provides only marginal corrosion resistance, but has a uniform black finish that does not alter the dimensions of the part after processing. The coating does not chip or peel and acts as an absorbent to hold oils or wax.

Black Oxide coatings are used on firearms, spark plugs, furniture brackets, mower blades and other products where a uniform black surface is desired. This coating is economical and offers a variety of valuable properties to extend the service life and improve the performance characteristics of the part.
