99.95% pure tungsten rods for vacuum furnace
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 polished
Purity:99.95%(min)
Density:19.3g/cm3
Dia:2.5-120mm
standard: 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.
We can manufacture according to your requests.
