1. Cobalt alloys have higher melting points than nickel (or iron) alloys, Which allows them to absorb stress at a higher absolute temperature.
2. Cobalt alloys give superior hot corrosion resistance to gas turbine atmospheres, due to their high chromium content.
3. Cobalt alloys show superior thermal fatigue resistance and weldability over nickel alloys.
---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.
