Black Oxide Firearm Finish
Commonly called ‘blueing’, this process oxidizes metal surfaces to a corrosion-resistant, decorative finish. The matte black finish is produced by a chemical reaction directly with the iron (Fe) in the steel to form the black oxide of iron ( Fe3O4). Robar® uses the latest chemicals containing new concepts in activators, catalysts, penetrants, inhibitors and rectifiers. The result is an attractive oxide-resistant finish on steel, including low and high carbon steels, alloy steels or hardened steels. Robar’s® process will not flake, chip, peel, or create any dimensional change. In using the latest technology in the Black Oxide process, Robar® is able to create a more corrosion-resistant, abrasive-resistant, attractive deep black finish. Robar® also guarantees that all specifications will meet or surpass all military, aeronautical and civilian specifications. Robar® offers all of these benefits at cost-effective prices. This process restores your old firearm to a like new condition. Please note Robar® offers this finish in matte only – we do not offer polished or bright polished blued finishes.
