Description
Extractor Nickel Boron AR-15
Manufacturers have been seeking to maximize corrosion protection and increase the hardness of their workpieces turned to hard chrome plating as a finishing technique. Chrome offers excellent resistance to corrosion and also protects against wear. However, concerns about the toxicity of the hexavalent chromium compound used to produce the chrome coating have forced manufacturers and metal finishing companies to search for a viable alternative to chrome. In turn, this has led to the development of a nickel-boron coating process.
