99.95% Pure Tungsten Rods Surface Black With Diameter 1mm to 120mm Length 1200mm

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.

Tungsten rods Surface Finish Available:

Black - Surface is \"as swaged\" or \"as drawn\"; Retaining a coating of processing lubricants and oxides. 

Cleaned - Surface is chemically cleaned to remove all lubricants and oxides. 

Ground - Surface is centerless ground to remove all coating and to achieve precise diameter control.
