Tungsten and alloys



Because of its very high melting point, tungsten is not molten but sintered. Its corrosion resistance is excellent and it is only slightly affected by mineral acids. Tungsten, used for wear parts in metallurgy, mining and the petroleum industry, has many applications. The metal’s hardness and density makes it perfect for metal alloys used in armament, heat pits and as a counterweight… Tungsten alloys: these refractory metals have the following compositions: W-Ni-Fe or W-Ni-Cu, or even W-Ni-Cu-Fe.

Technical characteristics


Improves resistance to fluxing and raises the recrystallization temperature compared to pure tungsten. WL is particularly suitable for electronics and more particularly for ion sources, lamp electrodes and welding electrodes.


Tungsten / rhenium alloy delivers greater malleability. Also, tungsten rhenium has a higher recrystallization temperature and better fluxing resistance. Several types of WRe alloys are possible, so please contact us for percentages. Especially adapted for uses >2000°C, in the aviation and aerospace industries.


This metal is specifically used for lamp and welding electrodes. It stands out because it offers even better properties at high temperatures.
