Drivers consistently report they can sense differences in how a car handles on the track if the weight on a given wheel varies only by a couple of pounds. Fine tuning a car to a given track is a very cumbersome and time consuming ordeal with conventional lead plate weights. WHA balance weight offers up to 50% more weight in a given volume, with the added advantages of direct attachment via threaded holes or thru-bolting and the freedom from deformation. The high density of WHAs permit weights to be placed in the lower half of NASCAR weight adjustment tubes, effectively lowering the overall center of gravity for improved handling. Tungsten product has a specialized line of racing weights for these applications.
 
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.

Tungsten alloy fishing weights are an ideal, environment-friendly alternative to lead weights, which are toxic and increasingly being labeled an environmental hazard. Tungsten alloy fishing weights are harder than steel and extremely dense, tungsten being on average 30 percent smaller than its lead counterpart. Tungsten alloy fishng weights are smaller than conventional weights, create twice the sound of lead weights and maintain their shape for longer. Tungsten is also used in the production of other fishing applications, such as tungsten-carbide line cutters and tungsten powder coating for fishing lines.
 
A fishing weight is a weight used to force a lure or bait to increase its rate of sink, anchoring ability, and/or casting distance. Fishing weights may be as small as 1/32 of an ounce for applications in shallow water, even smaller for fly fishing applications, or as large as several pounds or considerably more for deep sea fishing. They are formed into nearly innumerable shapes for diverse fishing applications. Environmental concerns surround the usage of most fishing sinker materials.

A jig is a type of fishing lure that usually consisting of a lead sinker with a hook molded into it and usually covered by a soft body to attract fish. However, recently, tungsten alloy fishing weights is becoming more and more popular among angles because it has the features of high density, small volume, and environmental friendly, and has been taking place of the lead sinker. Jigs are intended to create a jerky, vertical motion, as opposed to spinnerbaits which move through the water horizontally. The jig is very versatile and can be used in both salt water as well as fresh water. Many species are attracted to the lure which has made it popular amongst anglers for years.
 
The fishing weight is made by rare metal - Tungsten, it is an ideal substitute of the lead fishing sinker. It's strong adhesive, semi-solid state, soft for a long term. Tungsten Heavy Alloys concentrate maximum weight in the smallest possible space. They are more often to be used as counterweight in sporting field, such as fishing sinkers, golf weights, etc.

Owing to its high density of shielding, tungsten heavy alloys is quite ideal for medical radiation shielding of which including Magnetic Resonance Imaging(MRI),Intensity Modulated Radiation Treatment(IMRT ),Positron Emission Tomography (PET), collimator, isotope container, and so on. 

Tungsten heavy alloys for medical radiation shielding set forth below: 

The temperature of tungsten alloy material inside shaped charge liners rises from normal temperature to more than 1000℃ and strain rate reaches 1.0×10⁵s^-1. So, we can see that the shaping procedure of EFP (Explosively Formed Penetrator) is happening under the conditions of high temperature, high pressure and high strain rate. It is not any materials that can shape complete EFP. It has quite a high claims on the dynamic characteristics of materials under the condition of high temperature, high pressure and high strain rate. The ideal materials for shaped charge liners should have the properties of high melting temperature, high density, high elongation and dynamic strength, etc. Tungsten alloy material is ideal material for shape charged liners. Otherwise, engineering application also should considerate the cost and resources of material. Those materials which are important, high price and short resources are not easily utilized for a wide range.

Tungsten copper alloy shaped charge liners recombine metals which have different function so that can exert the complicated advantages of alloy. Compared with those single-metal shaped charge liners, tungsten copper alloy shaped charge liners have more reasonable transformation and absorption mechanism, more excellent penetration and lower cost. So it has wide prospect for development.

Tungsten alloy is adopted as projectile for EFP (Explosively Formed Penetrator) with its high density, high intensity and high ductility. Terminal sensing submunition can detect and distinguish targets in scanning area. When scanning trajectory of terminal sensing submunition scans the target in scanning area, the computer on the penetrator detonates warhead of EFP duly, forming explosive compacting tungsten alloy EFP projectile and attacks armor vehicles from top. Tungsten alloy EFP projectile flight trajectory is the trajectory that EFP projectile flies to the target.

Tungsten alloy EFP projectile is influenced by gravity and air resistance during flying. Gravity bends tungsten alloy EFP projectile flight trajectory and air resistance decreases the flight speed of tungsten alloy EFP projectile. High density of tungsten alloy can weaken the influence on projectile caused by gravity and air resistance. High density means higher density of energy and greater impact force, improving penetrating power. High ductility contributes to forming longer projectile so that highly increasing the depth of penetration. Because the flight speed of EFP is faster than sound velocity by 5~6times, the distance from detonating to target is no more than caliber by 1000 times. For that, the influence on EFP flight trajectory by gravity can be neglected. So tungsten alloy EFP projectile flight trajectory can be considered as straight line trajectory approximately and also can be described by using equation of motion for particle.

Tungsten alloy is used as collimator or radiation shielding in the following applications:

Geologging
Geologging is an exploration technique used mainly in the oil and gas industries. It is also known as wireline logging and borehole logging. A gamma ray source is lowered into a borehole and the radiation penetrates the rock strata. This data can then be analysed to determine whether deposits of gas or oil are present. Tungsten alloy is used to shield the radioactive source and to act as a collimator for the gamma beam.

Pipe-line Inspection
Gamma radiation is used to inspect welds and to detect cracks in pipelines. A gamma source is mounted on a remote-controlled wheeled trolley (sometimes called a "pig") and travels inside the length of the pipe. A tungsten collimator is used to direct the radiation onto the target, whilst the radioactive source is housed inside tungsten shielding.

Non Destructive Testing
Industrial radiography uses gamma radiation to detect structural faults in materials such as metal and concrete. As with pipe-line inspection, the equipment uses tungsten shielding, coupled with a tungsten collimator. Thickness, density and level gauging Radioactive sources are used in industrial processes to measure thickness, density or levels of materials during production e.g. paper, plastic film, steel sheet or surface coatings. The material passes between a radioactive source, which is housed in tungsten alloy, and a detector. The strength of the detector signal is used to measure the thickness, density or level of the material.
