Wolfram have the highest melting point (3410oC) of the four common refractory metals. with a density of 19.3 gm/ cc, it is only surpassed by rhenium and osmium in weight. Wolfram has a long history of use for filaments in the lamp industry. The material have the best high-temperature strength of all the refractory metals. For this reason, it is used in very high temperature vacuum furnaces.
