Tungsten alloy radiation shielding can be used for radioactive eliminator to protect staffs from radiation. Radioactive static eliminator is kind of electrostatic removing device which produces ray by utilizing radioactive isotope and ionizes ambient air into positive and negative ions. It gathers opposite charges on the surface of charged body in neutralization.

Radioactive static eliminator is build at the place which may cause static electricity. It releases rays constantly, ionizing air, producing positive and negative ions and changing into conductor. For that, a circuit is formed between the surface of body which cause static electricity and eliminator. Those ions neutralize static charge on the surface of body and eliminate static electricity. Radioactive static eliminator has been widely used for weaving, printing, papermaking, cigarette, rubber, plastic and electronics, sensitive film or other industries. It can be also used to eliminate ash on slide, photographic film, lianr and microbalance, etc.

Compared with lead, the density of tungsten alloy radiation shielding is higher than lead by 60%. High density allows a reduction in physical sizes of shielding components without compromising the effectiveness of shielding characteristics. High density also means better radiation absorption. Otherwise, tungsten alloy has the advantage of non-toxicity. So tungsten alloy is more suitable for radioactive static eliminator than lead.

Tungsten alloy shielding is necessary for irradiation linac. Electrons caused by irradiation linac are shielded easily for having small exit range. But they can cause strong bremstrahlung, being resisting by components of irradiation linac, cable as irradiated target, barrier plate, floor or other materials. Maximum energy of bremmstrahlung is possible maximum electron energy. Generally, irradiation linac will not cause photonuclear reaction and induced radioactivity, if energy is no more than 10MeV. For that, bremsstrahlung (X-ray) is primary target which must be shielded for irradiation linac.

Emissivity of X-ray caused by irradiation linac is relevant to electron energy, beam intensity, atomic number of target material, thickness of target or other factors and it changes with exit angle. For definite target material Z and thickness of target, emissivity of X-ray which is corresponding to unity beam intensity increases significantly with the increasing energy of accelerated electron and angular distribution of emissivity also changes with the increasing of electron energy.

Lead is used as traditional raw materials for radiation shielding. But lead has toxicity which may cause pollution. The density of tungsten alloy is higher than lead by 60%. The high density of tungsten alloy shielding allows a reduction in physical sizes of shielding components, without compromising effectiveness of shielding characteristics. Otherwise, tungsten alloy shielding has the advantages of non-toxicity. So compared with, tungsten alloy is more suitable for irradiation linac to shield against X-ray.

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. Tungsten alloy vehicle ballast as block shape 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 tungsten heavy alloys (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 alloy vehicle ballast, also called tungsten alloy vehicle weight, is now becoming the most popular material for balancing race cars.

Adding tungsten alloy vehicle ballast to the framework of a racing car helps you to balance the car during the race. Better balance contributes to the better control over the car's movement and helps to optimize the overall performance.

There have been many proposed applications for clusters of small Unmanned Aerial Vehicles (UAVs). Some of these applications, such as air antenna bases, Synthetic Aperture Radar and video surveillance, can generate large quantities of data which must be transmitted to a base station quickly. UAV size limitations often prevent the use of large, highly directive antennas in this link with the airborne antenna bases station. This paper proposes the solution of forming an array from several UAVs and applies antenna array theory to analyze its performance. An example is given where tungsten alloy is used to achieve high directivity even in the presence of element position errors. Tungsten alloy is the best material to make airborne antenna bases.

A tungsten alloy gyroscope rotor is a device for measuring or maintaining orientation, based on the principles of angular momentum. A mechanical they are essentially a spinning wheel or disk whose axle is free to take any orientation. This orientation changes much less in response to a given external torque than it would without the large angular momentum associated with the gyroscope's high rate of spin. Since external torque is minimized by mounting the device in gimbals, its orientation remains nearly fixed, regardless of any motion of the platform on which it is mounted. Solid state gyroscopes also exist.

Applications of tungsten alloy gyroscopes rotors include navigation (INS) when magnetic compasses do not work (as in the Hubble telescope) or are not precise enough (as in ICBMs) or for the stabilization of flying vehicles like Radio-controlled helicopters or UAVs. Due to higher precision, tungsten alloy gyroscope rotors are also used to maintain direction in tunnel mining.

Gyroscope rotors exhibit a number of behaviors including precession and notations. Tungsten heavy alloy gyroscope rotors can be used to construct gyrocompasses which complement or replace magnetic compasses (in ships, aircraft and spacecraft, vehicles in general), to assist in stability (bicycle, Hubble Space Telescope, ships, vehicles in general) or be used as part of an inertial guidance system. It effects are used in toys like tops, boomerangs, yo-yos, and Powerball's. Many other rotating devices, such as flywheels, behave gyroscopically although the gyroscopic effect is not used.

Tungsten alloy gyroscope rotors in operation have freedom of movement in all three axes. The tungsten alloy gyroscope rotors will maintain its spin axis direction regardless of the orientation of the outer frame. With its perfect properties, tungsten alloy is the perfect material for gyroscope rotors.

The popularity of adding tungsten alloy flywheel weights has increased dramatically. More and more riders discover that they can go faster for longer with the smooth power delivery, better traction, and reduced stalling that tungsten alloy flywheel weights provide. Adding a tungsten alloy flywheel weight will increase the rotating mass, or inertia, of the motor.

The result is an engine that is a little slower to rev, has more controllable power delivery and less hard hitting power, a more usable low to mid-range, and is less likely to stall at slow speeds or with the rear brake. What you will feel is better traction when it is slippery or hard pack, a torquier and broader power band, the top endpower on many bikes will be improved with less tendency to lose RPM's when climbing or hitting obstacles. The easier to control power will help you conserve your strength and energy, plus many bikes start easier with the added weight. Most can be installed in less than a half hour without removing the stock flywheel from the engine. Tungsten alloy flywheel weights are machined on computer operated lathes for the ultimate in balance, trueness and strength.
