Tungsten Sheet
Properties：
Tungsten has the characteristics of high melting point, high strength and hardness, high temperature performance, low resistivity, small expansion coefficient, small electronic work function etc., is the most widely used high temperature resistant metal materials .
- Information
Tungsten plate can be used to make: electrodes, heat elements, heat shield, Boats for electronics, and vacuum furnace.
1. tungsten are mainly used in metallurgy industry, mechanism process industry and rare earth smelting industry;
2.They are more frequently used in crystalloid materials and other burgeoning high-tech industries;
3.The tungsten should be used in vacuum or deoxidize atmosphere and the highest using temperature should be no more than 2000ºC.
