ASTM 99.95% Pure Tungsten Rod Straightened Wolfram Rods Diameter 1mm to 200mm
Tungsten metal features the lowest vapor pressure of all metals, very high module of compression and elasticity, very high thermal creep resistance, high thermal and electrical conductivity and, last but not least, a very high coefficient of electron emission. The latter can even be improved by alloying tungsten metal with certain metal oxides.
Pure Tungsten Rod Features:
Puirty 99.95%
Suface black or clean
Melting Point: 3410 Degrees Celsius
Boiling Point: 5927 Degrees Celsius
Surface roughness: < 1.6
Applications of Straightened Pure Tungsten Rod:
Suitable for producing ion implantation parts
For producing electric light source parts and electric vacuum components
For producing heating elements and refractory parts in high temperature furnaces
Used as electrodes in the field of rare earth metal industry
