For tungsten sheet, we have alkali cleaning surface and bright surface. For tungsten plate, we have polished surface. For tungsten boat, we have alkali cleaning surface. For tungsten tube, we have machined surface. For tungsten crucible, we have machined surface.

Normally, pure tungsten products can be used in the high temperature vacuum environment, so that they can exert their superior high temperature performance. If it is used in air condition under the high temperature of over 400 degrees, tungsten will react with oxygen and produce WO2. Because the melting point of tungsten is 3410 degrees, it can withstand up to 3300 degrees. But its normal working temperature is 1800~2600 degrees.

We can achieve the thinnest thickness of 0.025mm, and only a few factories in China can achieve this thickness.

(1)High density: 17-18.5g/cc; (2) High hardness and high strength; (3) High thermal conductivity and low coefficient of thermal expansion; (4) Good electrical and thermal conductivity; (5) Excellent machining performance; (6) Absorption capacity for X-rays and gamma rays; (7) For W-Ni-Cu tungsten heavy alloy, it is non-magnetic.
