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.
Application of Black Tungsten Rods:
For producing electric light source parts and electric vaccum components;
For producing heating elements and refractory parts in high temperature furnaces.
