Tungsten crucible is a crucible made of metal tungsten, which has the characteristics of high melting point, high strength and hardness, good high temperature performance, low resistivity, small expansion coefficient, and small electronic work function. Crucible is one of the important containers of evaporation coating equipment and optical coating equipment, mainly used for gold plating materials.
Advantages of machined tungsten crucible: high processing accuracy, precise size, good surface finish, and maximum melting consumption of plating materials
