Black Oxide

Blackening or Black Oxide is the process of chemically converting the surface of metal (usually steel) to a black oxide. Oxide is a term for rust, but if formed in the correct conditions will create a structurally patterned form of rust called oxide. The blackening process that we utilize is called a hot process. Which means that our blackening solution temperature is elevated to 285 degrees to accomplish the black oxide process.

The alternative that many people utilize is called a cold or room temperature blackening process. These can be obtained at many places often times cheaper, but be warned that many of these products will not hold a candle to our hot process and usually you get what you pay for in this case.

Key Benefits
