3/16 BLACK OXIDE CARDED

Black Oxide Coating: This is a conversion coating process that converts the surface of ferrous metals into a magnetite layer, which provides a black finish and prevents rust oxidation, Application: The coating is often used on various metal parts, including those from vehicles, to protect them from corrosion and give them a uniform, attractive appearance, Process: The parts are typically cleaned with brake cleaner to remove grease and oils, then submerged in a solution of black oxide concentrate and water. The solution is usually applied in a specific ratio, such as one part concentrate to nine parts water, and left to coat the metal surfaces.
