Tungsten Material Properties

There is an increasing demand of tungsten material from the electronics, nuclear, and aerospace industries for materials that maintain reliability under ever-increasing temperature conditions. Because its properties meet these requirements, tungsten also is experiencing an increasing demand.

Characteristics that support the demand for tungsten in many electronics applications are its:

● Strength and stiffness at high temperatures.

● Good thermal conductivity.

● Low thermal expansion.

● Low emissivity.
