ground Tungsten rods surface: black and polished Purity:99.95%(min) Density:19.3g/cm3 standard: ASTM

polished pure 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.

 Specification:

surface: black and polishedPurity:99.95%(min)Density:19.3g/cm3

Dia:2.5-60mmstandard: ASTM

Surface Condition:Black -Surface is black,retaining a coating of processing lubricants and oxides. Bright - Surface is chemically cleaned to remove all lubricants and oxides. Ground -Surface is centerless ground to remove all coating and to achieve precise diameter

Applications: For producing electric light source parts and electric vaccum components; For producing heating elements and refractory parts in high temperature furnaces.
