Tungsten processing Britannica

Tungsten processing, preparation of the ore for use in various products.. Tungsten exhibits a body-centred cubic (bcc) crystal lattice. It has the highest melting point of all metals, 3,410° C (6,170° F), and it has high conductivity for electricity. Owing to this unique combination of properties, it is used extensively as filaments for incandescent lamps, as electric contacts, and as

tungsten Uses, Properties, & Facts Britannica

Tungsten, chemical element that is an exceptionally strong metal. Occurrence, properties, and uses. The amount of tungsten in Earth’s crust is estimated to be 1.5 parts per million, or about 1.5 grams per ton of rock. China is the dominant producer of tungsten; in 2016 it produced over 80 percent of total tungsten mined, and it contained nearly two-thirds of the world’s reserves.

Cobalt processing The metal and its alloys Britannica

Cobalt processing Cobalt processing The metal and its alloys: In the production of a so-called cemented carbide, such as tungsten carbide, a briquetted mixture of tungsten carbide and cobalt powder is heated at a temperature above the melting point of cobalt. The latter melts and binds the hard carbides, giving them the toughness and shock resistance needed to make carbides of practical
