Tantalum tube has a high melting point reaching of 2996 ℃ and the density to be 16.68 g/cm3. Due to the high melting point, good corrosion resistance, cold working performance, tantalum tube and tantalum tungsten alloy tubes are widely used in chemical industry, high technology and atomic energy industry. Tantalum tube and tantalum tungsten alloy tubes mainly used to making reaction container and heat exchanger tubes for manufacturing chemicals, pipe, condenser, bayonet heater and spiral coil, U tube, thermocouple protection tube, and the liquid metal containers and pipes, etc.
