Cobalt Alloy Valve Ball
Cobalt Alloy Valve Ball Description & Application
Cobalt alloy valve balls are cobalt-based superalloys or cemented carbides and are often produced using smelting, casting or powder metallurgy processes. Due to the good ductility of cobalt-based alloys, it can be made into wire rods, rods and various castings (such as precision castings or centrifugal castings). Cobalt alloy valve balls manufactured by our company can withstand wear and corrosion in a variety of environments, and can be heat treated to further improve their wear resistance. And it can maintain the highest hardness at relatively high temperature is its unique advantage. Cobalt Alloy Valve Balls are often combined with matching valve seats for oil, gas, and chemical applications. in aerospace and marine engineering. Due to its excellent high temperature resistance, scratch resistance and corrosion resistance, Cobalt Alloy Valve Ball has unparalleled advantages in the application of drilling oil industry.
