Model No.: TH-1
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
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
For producing heating elements and refractory parts in high temperature furnaces.
