Tungsten Boats Evaporation Boats for Vacuum Metalizing

99.95 % Tungsten Products Tungsten Boats Evaporation Boats for Vacuum Metalizing

As a high performance materials, Pure Tungsten has high melting temperature, high density, low vapor pressure, low thermal expansion combined with good thermal conductivity, sufficient electrical resistance, high modulus of elasticity.

Tungsten boat is widely used in metallizing, electron-beam spraying as well as sintering and annealing in reducing atmosphere in electronics and light industries. Manufactured by the special production line in our corporation, tungsten boats can provide reliable guarantee of product quality for the users by adopting excellent tungsten materials with high purity, advanced techniques as well as special treatment to the product surfaces.

Tungsten boats are mainly used for evaporation or metalization of Al, Ni, Cu, Ag and many other metals in vaccuum furnaces.

Tungsten crucibles for quartz melting, sapphire growing furnace and high temperature vacuum furnace are also our main products.(including 35kg,65kg,85kg,120kg)

Tungsten bar
It can be used as high-temperature heat source and high-temperature structure accessory.

Main applications:
Manufacture electric light source and electric vacuum accessory.
It can be used for make electrical contact.For stirring purposes in rare earth metals smelting and for making tungsten contacts and parts in electrical light sources making.

Tungsten's unique properties, including a melting point of 3410ípc, low vapor pressure at elevated temperatures and low coefficient of thermal expansion, make it of value in a variety of high temperature products and processes
Among them are glass-to-metal seal parts and support parts for lighting and electronics, silicon rectifier stud mounts and high temperature furnace components.
Sifon produces pure and potassium doped (wk type) tungsten rod
The potassium doped products is targeted for use where high temperature non-sag properties are required in smaller cross sections by the lighting and electronic industries.
