~Features: high density polished pure tungsten crucible W liner
1.Tungsten crucible for vacuum coating is mainly used as containers and heating element for evaporation coating machine in optical glasses and spectacles field; high
2.It has great strength under high temperature, anti-friction corrosion resistance;
3.It also possesses high thermal conductivity, thermal expansion coefficient and good harden ability.
Application: high density polished pure tungsten crucible W liner
1.Tungsten crucible for vacuum coating products are widely used for smelting of rare-earth, quartz glass, electronic spraying, crystal growth and other industries; high density polished pure tungsten cr
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; high density polished
3.Tungsten crucible under turning forming is denser than sintered one.
