Tungsten Element, Alloys and Symbols

Tungsten is a rare acid-forming heavy metal found chiefly in the tungstates of iron and calcium, wolframite and scheelite.

The most important use to which tungsten is put is as a steelhardening metal. Tungsten steels hold their temper at, high temperatures and are therefore valuable for the making of highspeed tools, etc. Because of its high fusing point metallic tungsten is used as a filament in incandescent electric lights. Sodium tungstate is used in fireproofing cloth and as a mordant in dyeing.

Calciun tungstate is used as the luminous screen in X-ray apapparatus.
