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 .
