Cleveland Black Oxide provides a broad range of metal finishing services for automotive, architectural, hardware, machine tool, firearms, and ammunition industries, as well as both industrial and consumer products.

Depending on the post-treatment applied, black oxide coating can give corrosion resistance equivalent to 144 hrs of salt spray exposure.

The resulting lustrous black finish adds visual appeal and a "quality" image at a very low cost.

Cleveland Black Oxide offers moving machine parts, hand tools, and surgical instruments coated with black oxide that reflect less light and reduce eye fatigue when used under bright lights.
