Surface Treatment

Black Oxide

Black Oxide can be selected according to corrosion resistance, conductivity, appearance, assembly, and customer standards.

Finish Overview

Black oxide is used mainly on steel parts where a dark appearance and light surface protection are desired, often for mechanical fasteners and transmission parts.

Surface treatment should be selected together with the base material, service environment, appearance target, corrosion resistance, and assembly requirement.
