Tungsten is a metallic element that occurs in nature only as a constituent of certain minerals; it is never found in free or metallic form. USES The chief use of tungsten is in the production of alloy steels. In this field the most important single use is as a component of high-speed tool steels. Other important uses for tungsten steels are in the manufacture of drills, dies, valves, taps, and permanent magnets. A substantial proportion of the total consumption of tungsten is in the form of metallic tungsten used in the manufacture of electric light filaments. Minor quantities of tungsten are used for stellite, a nonferrous alloy, and for dyes, ceramics, fireproof cloth, fabrics, and X-ray screens. The principal tungsten minerals found in Arizona are the wolframites (ferberite, wolframite, and huebnerite); scheelite; powellite; cuprotungstite; and tungstite. Only the wolframites and scheelite have been of commercial importance. 54 p.Additional Links
