1. Cobalt alloys have higher melting points than nickel (or iron) alloys, This gives them the ability to absorb stress to a higher absolute temperature.
2. Cobalt alloys give superior hot corrosion resistance to gas turbine atmospheres, this is 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 temperatures up to 800
SYTOP cobalt base alloys are 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.
