Co42 Cobalt Based Self-Fluxed Alloy Powder Co55, Co42, Co50h, Co50

Cobalt based Co42 is a medium hard cobalt chromium tungsten alloy powder. Has good wear resistance, corrosion resistance and excellent red hardness, but the impact is poor, with hard alloy tool can be cutting. Suitable for plasma spray welding process, which is commonly used in the environment of 800 degrees below the environment has excellent wear resistance and corrosion resistance. Such as high temperature and high pressure valve, sealing ring, etc..
