Blackening, also known as black oxide coating, is a surface treatment process that involves the conversion of the surface of a metal to a black iron oxide. The process involves a chemical reaction that occurs on the surface of the metal, resulting in a dark, uniform finish.

Benefits of Blackening:

Corrosion Resistance

Blackening can provide a degree of corrosion resistance, making it useful for functional applications where corrosion resistance is important.


lackening provides a dark, uniform finish that can enhance the appearance of the metal and provide a decorative finish.

Reduced Light Reflection

Blackening can reduce the reflectivity of the metal surface, making it useful for certain applications where light reflection is undesirable.


Blackening can be applied to a wide range of metal substrates, including steel, copper, brass, and aluminum, making it a versatile process that can be used in a variety of industries and applications.


Blackening is a cost-effective process that can be easily integrated into existing production processes.
