The tungsten heavy alloy has the excellent mechanical properties such as the high vibration-damping capacity. They also have the high density and excellent radiation-shielding property. At the meantime, the tungsten heavy alloy has the high thermal conductivity with the low thermal expansion coefficient.
The tungsten heavy alloys (WHAs) are tungsten alloys that typically contain 90 to 98wt%. Most commercial tungsten alloys are two-phase structures. The principal phase is nearly pure tungsten in association with a binder phase containing the transition metals plus dissolved tungsten. As a consequence, WHAs derives their fundamental properties from those of the principal tungsten phase, which provides for both high density and high elastic stiffness. It is these two properties that give rise to must applications for this family of materials.
