Cobalt Alloy Bar

cobaltalloy have higher melting points than nickel (or iron) alloys ,This gives them the ability to absorb stress to a higher absolute temperature.

Cobalt alloys give superior hot corrosion resistance to gas turbine atmospheres , this is due to their high chromium content.

Cobalt alloys show superior thermal fatigue resistance and weldability over nickel alloys.

Cobalt Alloy Bar —Excellent wear and corrosion resistance even at high temperature up to 800℃

SYTOP cobalt base alloys is a range of cobalt-chromium-tungsten alloys with wear resistance, corrosion and high thermal resistance. It is widely used in oil & gas, machinery, wood cutting, automotive, paper and food processing industry etc.
