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. Black oxide penetrates the steel 5-10 thousandths and adds to the part thickness by only 5-10 thousandths providing a hardness of 5 on the Mohes scale.

Cincinnati Black Oxide utilizes a hot black solution, with our tank operational at approximately 285ºF. Our Black Oxide is heated via a 1.2 million BTU burner system and is temperature controlled automatically. Utilization of our own chemistry in the tank gives us total control over the quality of our plating. Our VBS Black Tank chemical process produces a fine grained uniform surface. Contamination of our black tank is controlled by skimming of suspended oxides regularly. This contributes to our consistent high quality finish.
