High-Temperature Tungsten Bright Sheet – Exceptional Thermal Stability and Precision Dimensions

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.
