high purity melting pot crucible tungsten crucibles for vacuum coating industry
According to different processing methods, crucibles can be mainly divided into sintered molding, press molding, spinning molding, turning forming and welding forming. It is mainly made from turning forming. Tungsten crucible for vacuum coating refines from W-1 powder.
Tungsten crucibles for vacuum coating are widely used for the sapphire single crystal growth furnace, quartz glass, melting furnace and rare-earth smelting furnace industrial.
tungsten crucibles by turning forming are widely used for smelting of rare-earth, quartz glass, electronic spraying, crystal growth and other industries.
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 with inferior intensity.
tungsten crucible for vacuum coating is of high-purity, high-density, high heat resistance.
Our products are made with precise size, smooth inner and outer surface.
