Tungsten bar is mainly used to found ingredient of material, cutter and heads, tungsten wire for lights instruments, electric contact points and conductor of heat, crankshaft and cylinder barrel of advanced automobile, ingredient of kinds of heat-resistant steel. Also used for making special steels, to make guns, artillery rockets, satellite airplane and ship. It has a luster rather like that of silver in uniform color. Though the whole bar may slightly curve, the maximum height of the bend should not be more than 7mm.

Tungsten bar with impurities is used to procedure bulb filaments or electron tube filaments, which are guaranteed to have remarkable resistance to high temperature.

Tungsten is a naturally occuring metal. Tungsten can be used either in pure form or mixed with other metals to make alloys.

Tungsten alloys tend to be strong, and resistant to heat and wear. Tungsten and its alloys are used in a variety of commercial products including loght bulb filaments, X-ray tubes, welding electrodes, grinding wheels and ceramic pigments.

Tungsten has been used without ill effects as a component in US food and Drug Administration (FDA)-approved medical implants such as orthopedic hardware and tungsten coils for heart defects. Numerous countries have used tungsten and various tungsten alloy munitions for a number of years because of its high density and ability to penetrate armor.

Initially, tungsten carbide was used in munitions, but newer composites such as tungsten/nickel/cobalt and tungsten/nickel/iron have superior properties.

Tungsten, from the Swedish tung sten meaning ‘heavy stone'; chemical symbol W, was first isolated in 1783. The heavy alloys of this hard, dense metal should not be confused with tungsten carbide, as used in cutting tools. These alloys typically contain 90 - 97 wt%, hence deriving their fundamental properties from tungsten. As a result, WHAs are becoming the materials of choice for designers and engineers who require such properties as high density, good mechanical strength and ease of machining for use in radiation shielding and collimation and above all, counterweights and ballast.

Therefore, tungsten added with Ni, Fe, Cu is very suitable matreial for counterweights.
