Black Oxide

black oxide finish from anoplate, AMS 2485, MIL C 13924

What is Black Oxide?

Black oxide is a type of conversion coating that provides metals with a matte black appearance and dimensional stability. Black oxide can also provide corrosion resistance for equipment, gear or parts when the treated metal is oiled.

A conversion coating generally describes a coating process that is completed through a chemical or electrochemical treatment of a metal surface. Black oxide is not the only type of conversion coating; conversion coatings include phosphate and chromate conversion coatings, among others.

What are the Benefits of Black Oxide?
Applying a black oxide finish offers many essential benefits to ensure smooth operations of equipment, devices, components and much more. 

Protection From Corrosion - When oiled or waxed, a black oxide finish helps to prevent corrosion. This protection from corrosion can be vital for error-free functioning, providing reliable and long lasting use.

A High Quality, Black Appearance - For discretion, essential functioning and more, sometimes your metal needs to feature a black appearance. Black oxide provides a high quality, black aesthetic at low production costs. Black oxide offers a durable way to make a metal black, avoiding chipping and other forms of corrosion that can occur from other blackening methods. 

Dimensional Stability - A black oxide finish is extremely thin, providing 10 millionths of an inch at maximum to the dimensions of your metal. This minuscule addition does not effectively change your metal's dimensions, providing the benefits of a black oxide finish while maintaining your intended function and appearance.

A Cost Conscious Solution - Black oxide provides all of the above benefits at a reduced expense, making black oxide a great solution for organizations that are working with tight or fixed budgets. 

Common Applications for Black Oxide

Black oxide is used in a variety of industries and applications. From providing the appearance and corrosion resistance needed on the battlefield, to essential functioning for medical and surgical tools and much more, black oxide is a versatile metal finish.

Common uses for black oxide include, but are certainly not limited to: 

  • Essential finishes for firearms, for both the defense industry and commercial markets
  • Precision tools
