99.95% pure Tungsten bars for vacuum furnace

99.95% pure Tungsten bars for vacuum furnace Tungsten has the highest melting point of all metals and is therefore also suitable for very high-temperature applications. It is also characterized by a uniquely low coefficient of thermal expansion and a very high level of dimensional stability.   surface: black and polished
Purity: ≥ 99.95% Density: ≥ 19.2g/cm3, Surface roughness:< 1.6 Dia: 2.5-120mm
standard: ASTM   Tolerance:

Diamenter(mm)	Tolerance(mm)
	Black rod	Ground
<=5.0	±2	±0.03
5	±2	±0.05
>5.0-8.0	±2	±0.05
>8.0-16.0	±2	±0.08

  Application: Used in the manufacturing of electric light source and electric vacuum parts and get an electric shock materials Used as a means of high temperature and high temperature structure parts In the rare earth industry used as electrode   before quotation, please let us know the diameter, length and surface of tungsten rod you need.

We can manufacture according to your requests.
