In 1781, the Swedish chemist, Carl Scheele discovered tungsten acid, and Torbern Bergman concluded that a new metal could be prepared from the acid.Tungsten metal was first isolated in 1783 by the Spanish chemist and mineralogist brothers Juan JosÚ and Fausto Elhuyar. W stands for "Wolfram". Uses - drill bits, light bulb wire, electrical contacts, x-ray targets, windings and heating elements for electrical furnaces
