Cobalt (Co) - Chromium (Cr) based alloys are known for exhibiting a superior combination of corrosion resistance, erosion resistance, galling resistance, and high temperature strength. They have found a wide variety of applications in automotive, aerospace, chemical and biomedical applications. They are frequently known as the Stellite† grade of families (ex: Stellite† 1, Stellite† 6, Stellite† 12, Stellite† 21, etc.) and are broadly classified into the Co-Cr-Mo-C and the Co-Cr-W-C systems. The relatively high Carbon (C)and Tungsten (W) containing (Co-Cr) alloys are mostly used for their high wear properties.
