Tungsten is a heavy metal that can be classified as a refractory metal, i.e., one with a high melting point. Refractory metals can be useful for their strength at high temperatures and their resistance to corrosion. Tungsten is difficult to melt, so commercial non-alloyed tungsten is produced by powder-metallurgy methods.
Alloys containing about 85 to 95 percent tungsten by weight can be produced by liquid-phase sintering compacts of tungsten powder with nickel-copper, iron-nickel, iron-copper, or nickel-cobalt-molybdenum binders. In compact forms, these tungsten alloys can be machined by turning, drilling, boring, milling, and shaping; however, they cannot be wrought at any temperature and therefore are not available in mill forms. Heavy tungsten alloys can be used in aircraft applications, by the military in its weapons, in X-ray shielding, and even some consumer goods applications.
Light bulb filaments are usually made of unalloyed tungsten. Cutting tools are often made of tungsten carbide. Finally, tungsten is also an element of some of the modern super alloys.

Pure tungsten is a gray-white hard metal with a number of medical, industrial, and defense applications. For example, tungsten is important to the metalworking industry as a component of tungsten carbide, which is used to make abrasion resistant cutting tools. Tungsten metal wires are used extensively as filaments in incandescent lighting.
The defense industry uses tungsten heavy metal alloys in armaments, and medical applications for tungsten include radiation shielding. Tungsten is also used in pigments. The metal appears as number 74 in the periodic table of elements, and its chemical symbol is W, for tungsten's original name, "Wolfram."
The word tungsten itself is Swedish for "heavy stone," and gives an indication of the metal's high density. Like other refractory metals, tungsten has an extremely high melting point. Tungsten oxidizes in air at temperatures as low as 190° Centigrade, which means that in spite of its heat resistance, it requires protective coating if it is to be used at high temperatures. Like other refractory metals, tungsten retains its high yield and tensile strength at elevated temperatures.

Tungsten is used in applications as diverse as pigments, electrical contacts, light bulbs, weaponry, and abrasion resistant tools. The lion's share of tungsten is produced in China, and it is Chinese economic activity that arguably has the greatest effect on tungsten metal prices. When China has flooded the market with tungsten export, prices have historically fallen, sometimes precipitously.
China, however, has recently been depressing tungsten exports, increasing domestic consumption, and switching focus towards producing more tungsten finished goods. Consequently, tungsten metal prices have risen dramatically in 2005.
Meanwhile, North American Tungsten, a Canadian tungsten supplier, has reorganized after encountering previous financial pressures, and is now poised to supply more tungsten to the world market. With tungsten metal prices exceeding their previous historical highs in 2005, it's possible that producers in other areas of the world with tungsten reserves (such as Vietnam) will come online to take advantage of the current favorable economics.
Even with the possibility of increased production outside of China, however, tungsten buyers should be prepared for tungsten prices to remain high for the foreseeable future. Indeed, some economic forecasters feel upward price pressures on raw materials represent the new reality, and an increasing economic trend.
