As a high melting point metal, Ta possesses a low vapour pressure and good electrical and thermal conductivity up to very high temperature. The advantages of Ta are excellent corrosion resistance, high high-temperature strength, good machinability and good biocompatibility.
Tantalum and Ta-Alloy are mainly used for Heat Exchangers, Shell and Tube Heaters, Bayonet Heaters, Condensers, vessel liners, Sputtering Targets, Cathode Protection Systems for steel structures such as bridges, water tanks, Corrosion Resistant Fasteners, High Temperature Furnace Parts, Nuclear Reactors, Aircraft and Missile Parts.
