high purity sintered tungsten melting pot crucible tungsten crucibles for sapphire furnace
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.
(1) Sintering tungsten crucible:
Density: 18.5~18.8g/cm3
Working Temperature: 1800~2600DC
(2) Forging Tungsten Crucible:
Density: 18.9~19.2g/cm3
Woring Temperature: 1800~2600DC

It is widely used is high termperature furnace, because of the high purity and high temperature resistance. And it has long service life.
As the manufacturer, firstly, we have very good quality control system, the products will be inspected by each step including the surface, the dimension, crack, or other inspection item as cumtomer requires.
Secondly, as a factory, our price has obvious advantages. We'd like to make our customer purchase good quality products with good price. It's a win-win business.
What's more, we have full after sales service. In case there is a quality problem, we are responsible. And we will do our best to solve the problem to make our customer satisfied.
We have kinds of inspection equipments. Such as CMM, ultrosonic inspection, hardness tester, metallography analysis apparatus etc.
tungsten crucible will be packed with soft kraft paper first to protect the surface.
To ensure the safety during transportation, products will be packed accordingly with exportable wooden box with foam sheet protection inside.
If customer has special packing requirments, we will try to meet them.
Note: When you received the products, open the package carefully, some parts are sharp, please protect yourself. And if there is any damage, remember to contact with us, we will solve the problem for you.
1. How do you insure the quality is good?
