Tungsten-Molybdenum Precious Metal Alloys Overview!

Tungsten and molybdenum are refractory metals of the same group. The theoretical density of tungsten is 19.35 g/cm³, with a melting point of 3410±20°C. Molybdenum has a theoretical density of 10.2 g/cm³ and a melting point of 2610°C.

Wolfram-molybdenum smelting typically involves three methods: powder metallurgy, electron beam melting, and vacuum arc melting. While the latter two methods involve melting processes, one does not. However, in terms of application scope and material properties, powder metallurgy holds a dominant advantage. This is also due to the natural advantage of powder metallurgy in controlling the morphology of metal grains and producing dispersion alloys, which is not available in melting processes.

The process of rolling and forging plays a crucial role in the final density and grain orientation of materials. Due to the poor ductility of tungsten-molybdenum products, machining them is relatively challenging.
