Cobalt alloys 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.This factor is the primary reason cobalt alloys are used in the lower stress, higher temperature stationary vanes for gas turbines.

Cobalt alloys' combination of high melting points, excellent mechanical properties, corrosion resistance, and other unique characteristics make them versatile and indispensable materials across diverse industries. Their use continues to expand as technology and engineering advancements demand materials capable of withstanding increasingly demanding conditions.
