Hafnium Flat Products Description
Hafnium has good corrosion resistance and high strength. It resists corrosion due to formation of a tough, impenetrable oxide film on its surface. Hafnium is unaffected by alkalis and acids, except hydrofluoric acid. Hafnium is difficult to separate form zirconium, because the two elements have atoms that are the same size.
Hafnium applications include nuclear reactors, nuclear submarines, medical treatment equipment, fuel cells, solar energy.
