The tungsten alloy crankshaft is placed on the balancer and spun to determine the points where metal needs to be added or removed. The balancer indexes of the crank show the exact position and weight to be added or subtracted. The electronic brain inside the balancer head does the calculations and displays the results. The tungsten alloy crankshaft counterweight is done by two inserts which are made of tungsten alloy, to improve acceleration. Common method is adding light elements such as silicon to reduce the weight of the crankshaft.

Tungsten alloy crankshaft brick typically connects to a flywheel, to reduce the pulsation characteristic of the four-stroke cycle, and sometimes a tensional or vibration damper at the opposite end, to reduce the torsion vibrations often caused along the length of the tungsten alloy crankshaft brick by the cylinders farthest from the output end acting on the tensional elasticity of the metal.

Using tungsten alloy crankshaft brick can also be cost effective with some crankshaft designs. Since the raw steel stock needed for the crankshaft can be much smaller if it does not need to include the counterweights. It also makes it easier to machine the crank pins hollow without having counterweights in the way.

With regards to tungsten’s properties, it is a very dense metal with a high Moe, so it makes a more compact counterweight mass. If the tungsten alloy crankshaft brick counterweights are radically bolted, fatigue is not much of a problem since the bolt loads are not reversing.

Scientists think that tungsten is much less toxic than lead or mercury. Tungsten has been shown to act by antagonizing the action of the essential trace element, molybdenum. Long industrial experience has indicated no pneumoconiosis to develop among workers exposed solely to W or its insoluble compounds.

In order to protect patients, doctors, nurses and other people who maybe exposed to radiation, sources of the radiation must be safely separated and shielded. It is crucial that holding and delivery instruments for radioactive materials would keep the radiation levels low enough, not to create harmful effects of ionizing radiation such as breast cancer, skin cancer, etc. Lead and steel are the traditional protection materials, but tungsten alloy radiation shielding is without a doubt the best solution. Excellent radiation-absorption, twice the
density of lead and good physical resistance is main reasons to use tungsten alloy radiation shielding. Tungsten alloy health is a hot topic for environment protection and human protection from radiation.

The tungsten generator shields contain a radioactive core loaded with an isotope called molybdenum 99, which decays to a daughter isotope, technetium 99m. This radioactive fluid is collected and diluted with sodium chloride, mixed with a range of diagnostic agents, and injected into patients. The radioactive substance collects in certain parts of the body and can be viewed by a gamma camera. The parent molybdenum 99 has a 2.75-day half-life, while the daughter isotope has a half-life of only 6 hours, minimizing its time in the body.

Supplied with knurled and brass-threaded closures, leaded glass viewing windows, and our ergonomic non-slip finish, these tungsten generator shields provide the optimum solution for “milking” your generators.

X-ray computed radiography (CR) is kind of digital imaging technology using tungsten alloy imaging plate (IP) as carrier for X-ray image. The most important characteristic of CR system is that it is made of tungsten alloy IP, the new generation for X-ray image which is different from film, carrier utilized by traditional shadowgrap. The new carrier has high sensitivity and latitude to X-ray.

But tungsten alloy IP cannot produce visible light directly after absorbing X-ray. It produces stable sub-image and store inside crystal of tungsten alloy IP after collecting analog signal of X-ray. Sub-image can be read when being scanned by photoluminescence. Conversion of signal output by tungsten alloy IP is finished. Then signal forms digital image after being dealt with by computer. The final image can be shown on fluorescent screen or printed on film, heat sensitive paper or others, besides storing in disc and system.
