Product Description

99.95% pure Tungsten heating elements:
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%
Density: 19.3g/cm3,
Surface roughness: < 1.6
Dia: 2.5-120mm
