About 65% of the cobalt used in the United States is used to make alloys, primarily superalloys .
Another 20 to 25% is used as alloy additions in nickel-base superalloys and heat-resisting steels.
Look at detector materials - the first medical X-ray tube - or superalloys or advanced ceramics or thermal barrier coatings that make it possible to run aircraft engines and power systems at higher temperatures and higher efficiencies.
The effect on microstructure is not nearly so clear in other cases where a well defined substructure is produced, e.g. Al-Mg alloys, ferritic Fe-Si, Fe-Cr and Fe-Ni alloys, austenitic stainless steels, and nickel superalloys .
While others in the market readily acknowledged that demand from the stainless steel sector is slack, order books for nickel-bearing engineering steel and superalloys are strong, they said.
