More info

Spherical Cobalt-Based Alloys Powder (CoCrMoW) is a cobalt-chromium alloy powder, known as cobalt-chrome-tungsten (molybdenum) or Stellite( an alloy invented by Elwood Haynes in 1907). It consists of elements such as Mo and W based on Co and Cr. It also contains a small amount of Si, Fe, etc. It is a hard alloy that can resist various types of wear, corrosion, and high-temperature oxidation.
