Tungsten is one of our main product.

It has the highest melting point (3410°C) of the four common refractory metals.

with a density of 19.3 gm/ cc, it is only surpassed by rhenium and osmium in weight.

Tungsten has a long history of use for filaments in the lamp industry.

Tungsten has the best high-temperature strength of all the refractory metals.

For this reason, it is used in very high temperature vacuum furnaces
