Specifications

Polished tungsten rods
surface: black and polished
Purity: 99.95 %( min), Density :> =19.2g/cm3,
Dia: 2.5-120mm
Standard: ASTM

Polished/ground Tungsten rods:

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
