The melting point of tungsten is the highest of all metal elements, and its density is 19.3 g/cm ³) It is very high, close to gold, and the hardness of tungsten is also very high. For example, the hardness of tungsten carbide is close to that of diamond. In addition, tungsten has good conductivity and thermal conductivity, small expansion coefficient and other characteristics, so it is widely used in alloys, electronics, chemical industry and other fields
