It is characterized by high density, high strength, strong radiation absorption ability, high thermal conductivity, low coefficient of thermal expansion, good electrical conductivity, plasticity, thermal conductivity, weldability and machinability, and a certain degree of ferromagnetism. Tungsten alloy is composed of a soft binder phase and hard tungsten grains, and welding is required at the joints during processing.
