Fine Tungsten Filament

The melting point of tungsten is the highest among all metal elements, the density (19.3 g/cm?) is very high, close to that of 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 also has good electrical and thermal conductivity, small expansion coefficient and other characteristics, so it is widely used in alloys, electronics, chemical industry and other fields. Among them, cemented carbide is the largest consumer field of tungsten.

Application of tungsten in steel field
Tungsten steel milling cutter The hardness of tungsten is very high, and the density of tungsten is close to gold, so it can improve the strength, hardness and wear resistance of steel. It is an important alloy element and is widely used in the production of various steels. Common Tungsten-containing steels include high-speed steel, tungsten steel, and tungsten-cobalt magnet steel with high magnetization and coercive force. These steels are mainly used to manufacture various tools, such as drill bits, milling cutters, drawing dies, female dies, and male dies. wait.
