Hafnium alloy, and can be used for rocket nozzles aircraft gliding reentry leading edge protective layer, Hf-Ta alloy tool steel and can be fabricated of resistive material. In heat resistant alloy of hafnium is used as add elements, such as tungsten, molybdenum, tantalum alloys Some of hafnium increases. Because of the high melting point and hardness HfC, increasing agent can be used as carbide. 4TaC HfC a melting point of about 4215 ℃, the highest known melting point of the compound.
Hafnium Plate , Rod , Wire , Pellets , Cylinder can be used as evaporation material, sputtering target .
