Description
According to different processing methods, tungsten crucibles for vacuum coating can be mainly divided into sintered molding, press molding, spinning molding, turning forming and welding forming. Turning forming is mainly applied.We recommend the working temperature of the tungsten crucible for vacuum coating should be controlled below 2600℃.We can produce tungsten crucibles according to the customer drawing.
Features
1. Tungsten crucible for vacuum coating is mainly used as containers and heating element for evaporation coating machine in optical glasses and spectacles field.
2. It has great strength under high temperature, anti-friction corrosion resistance.
3. Tungsten crucibles also possess high thermal conductivity, thermal expansion coefficient and good harden ability.
Application
1. Tungsten crucible for vacuum coating products are widely used for smelting of rare-earth, quartz glass, electronic spraying, crystal growth and other industries.;
2. Generally, sintered tungsten crucible is large while the forged one is small; the wall of rolled tungsten crucible is thin; welded tungsten crucible is cost-effective but owns inferior intensity.
3. Tungsten crucibles under turning forming are denser than sintered ones.
