UNICO provides a uniform black oxide chemical conversion coating on ferrous and non-ferrous materials using DOD certified standards. MIL-C-13924D and AMS-2485 are the specification for a uniform coating for ferrous metals. Mostly decorative coatings, they also provide some corrosion protection.
Our black oxide services are designed to accommodate both high volume and small production runs with capability to rack and barrel process.
Parts are individually placed prior to plating for special care handling.
Parts are tumbled together, generally for high volume runs.
