Tungsten Ore Applications

The main component of tungsten ore is tungsten.Tungsten is a dull silver-colored metal with the highest melting point of any pure metal.Also known as wolfram, from which the element takes its symbol, W, tungsten is more resistant to fracturing than diamond and is much harder than steel. It is the refractory metal's unique properties - its strength and ability to withstand high temperatures - that make it ideal for many commercial and industrial applications.

Applications:

Tungsten's primary application for over 100 years has been as the filament in incandescent light bulbs. Doped with small amounts of potassium-aluminum silicate, tungsten powder is sintered at high temperature to produce the wire filament that is in the center of light bulbs that light millions of homes around the world.

Due to tungsten's ability to keep its shape at high temperatures, tungsten filaments are now also used in a variety of household applications, including lamps, floodlights, heating elements in electrical furnaces, microwave ovens, x-ray tubes and cathode-ray tubes (CRTs) in computer monitors and television sets. The metal's tolerance to intense heat also makes it ideal for thermocouples and electrical contacts in electric arc furnaces and welding equipment. Applications that require a concentrated mass, or weight, such as counterweights, fishing sinkers and darts often use tungsten because of its density.
