Tungsten heavy alloy (WHA) balance weight of racing car is now becoming the most popular material for ballast, due to its main advantages as follows:

Highest density
Adding WHA balance weight into the whole framework of a racing car is helpful to optimize the performance of the racing car during the racing progress, which contributes to the better control of the car's movement.

High tensile strength and good creep resistance
Tungsten has high tensile strength and good creep resistance with a high mass/size ratio, so it will be the ideal to work in a restricted space. Its high density also gives enhanced sensitivity by increasing the control of load distribution.

Machined Easily
WHA is also easily machineable which gives designers greater flexibility in deciding on the final shape of components and offer designers several advantages over conventional balance materials e.g. lead or steel.

With efforts underway to ban lead-based ammunition as a potential health and environmental hazard, scientists are reporting new evidence that a prime alternative material for bullets -- tungsten alloys-- may not be a good substitute The report, which found that tungsten alloys accumulate in major structures of the immune system in animals, appears in ACS' journal Chemical Research in Toxicology.

Jose Centeno and colleagues explain that tungsten alloys have been introduced as a replacement for lead in bullets and other munitions. It resulted from concern that lead from spent ammunition could harm wildlife when it dissolves into water in the soil, streams, and lakes. Scientists thought that tungsten alloys were relatively non-toxic, and a "green" replacement for lead. Recent studies suggested otherwise, and with small amounts of tungsten alloys also used in some artificial hips and knees, Centeno's group decided to gather further information on tungsten alloys.

They added small amounts of  tungsten compound to the drinking water of laboratory mice, used as surrogates for people in such research, and examined the organs and tissues to see exactly where tungsten ended up. The highest concentrations of tungsten were in the spleen, one of the main components of the immune system, and the bones, the center or "marrow" of which is the initial source of all the cells of the immune system. Further research, they say, will be needed to determine what effects, if any, tungsten may have on functioning of the immune system.

Tungsten alloy in high temperature tooling is called as tungsten alloy extrusion dies and die casting components.

Tungsten alloy can save time and money in hot metal working. The high tungsten content offers good resistance to thermal cracking, erosion, soldering and the effects of heat cycling in hot metal working processes. Experience has shown that, due to its non-wetting properties, tungsten alloy has significantly increased longevity over the equivalent parts in steel or cast iron. Tungsten alloy does not require heat treatment before use.

Tungsten alloy can save time and money in the extrusion of copper and copper alloys because its high tungsten content offers good resistance to metal pick up, erosion, soldering and the effects of heat cycling such as thermal cracking. This significantly increases the operating life of die inserts compared to the same components made from steel or stellite.

In recent years, there has been an increased desire to replace depleted uranium (DU) anti-armor penetrators with tungsten heavy alloy (WHA) penetrators. However, the ballistic performance of WHA does not compare with that of DU.

Many methods of improving the ballistic properties of tungsten heavy alloys have been explored. One recent method includes jacketing a long thin core of WHA with a more ductile metal. However, applying thermal-sprayed coatings onto a tungsten substrate is a challenge. The differences in the coefficients of thermal expansion (CTE) make it difficult to achieve adequate adhesion of most coatings to tungsten. Further compounding the problem are residual stresses inherent in thermally sprayed coatings. The thicker the coating desired, the more likely disbonding will occur upon cooling of the substrate. Early attempts to apply an Ni coating (0.0lOA).020 in thick) to a tungsten substrate yielded immediate disbonding and/or cracking of the coatings. The work presented is an investigation focusing on modifications to spray parameters and the use of multiple thin layers to minimize heat transfer and achieve better adhesion.

The use of a material with a CTE nearer to that of tungsten heavy alloys as a bond coat and grading of coating materials was also examined as a method for increasing the overall adhesion of the coating system.

Tungsten heavy alloys comprising by weight from about 80 to about 100% tuten and from about 0 to about 20% of one or more heavy alloying metals are produced by introducing powders of tungsten and the alloying metals into a thermal spray plasma gun, melting the powders in the hot zone of the gun to form a molten alloy and then spraying the molten alloy in droplet form into a collecting chamber where the droplets are solidified, and the resultant alloy in powdered form is collected. The powdered alloy can be further mixed with powdered copper, iron, nickel, cobalt or tantalum and compacted by dynamic or explosive compaction to form a near full density material. Full density materials are produced by further thermomechanical processing of the compact.

Tungsten heavy alloys, which are of great value in counter weights for aircraft, in ballistics, and in other applications, are conventionally produced by liquid phase sintering of mixed elemental powders. Alloys produced by this method are generally two-phase composites consisting of rounded tungsten grains dispersed in an alloy metrix.

The mechanical properties of tungsten heavy alloys are strongly dependent upon their specific microstructural features: for example, the grain size, contiguity, dihedral angle and the volume fraction of the tungsten phase. For a given tungsten content, the optimal microstructure exhibits low contiguity, small grain size, and strong W-W grain boundary and W-matrix interface.
