Pure tungsten rod

Description of tungsen rod bar
can be manufactured in random length pieces or cut to meet customers’ desired lengths. There are three different surface processes which are provided upon the desired end use:
1. Black tungsten bar – Surface is “as swaged” or “as drawn”; retaining a coating of processing lubricants and oxides;
2. Cleaned tungsten alloy bar- Surface is chemically cleaned to remove all lubricants and oxides;
3. Ground tungsten bar Surface is centerless ground to remove all coating and to achieve precise diameter control.

Features:
The outstanding feature of 99.99% tungsten bar is that they can be batch operated. Among the rod-like metal materials, tungsten bar has the highest melting point. In heat, electric conduction and electron emission, it performs very well. The tungsten bar is also characterized by high density, low dilatation coefficient and lowest metallic vapor pressure.he density of our tungsten bar is higher than 18.8g/cm3; purity, 99.5%. This has met the GB 4187-84 and AKM QB/WB-2006 Standard.

Theoretical density: 19.3g/cm3
Melting Point: 3422℃
Electric condctivity: 30% IACS Min
Rigidity: 69 HRA Min
