Designers can now enjoy high density, excellent mechanical strength and easy machining of the material. The same material is used in space flight and national military industry. The tungste heavy alloy is the best choice to be used as counterweight. Compared with lead,tungsten has smaller volume,so tungsten's resistance in the water is smaller than lead,which will make the yacht move ahead more quickly. Tungsten alloy yachts counterweights vary in size and shape.

The high density of the tungsten heavy alloy make contribution to reduce the physical size of the module, make it easier to control the distribution of the weight, enhance the flexibility of the control mechanism.When large mass has to be confined into very small space in the yacht,tungsten alloy yachts counterweights become the best choice.Tungsten alloy yachts counterweights are non-toxic and environmentally friendly. They successfully replace the toxic products such as lead.And tungsten alloy yachts counterweights can keep their shape unchanged for a long time.We can provide all kinds of tungsten alloy yachts counterweights according to your requirements.

Tungsten alloy is ideal for shielding against X rays and gamma radiation. The very high density of tungsten shielding (more than 60% denser than lead) allows a reduction in the physical size of shielding components, without compromising their rigidity or the effectiveness of the shielding characteristics.

Tungsten heavy alloy shielding is used in applications such as collimator, nuclear shielding, beam stop, PET syringe shield, vial shield, isotope container, FDG container, multi leaf collimator etc.

Positron emission tomography  is one of the nuclear medicine techniques available for diagnosis. Whilst X-rays provide information on the structure of the body, PET shows the chemical function of a particular organism.  As the
travels through the patient’s body it emits gamma radiation which is detected by a gamma camera, from which the chemical activity within cells and organs can be seen. Any abnormal chemical activity may be a sign that tumours are present.

Radiotherapy destroys cancer by directing beams of radiation directly onto the tumour. The beams of radiation require a very fine focus to avoid harming the surrounding healthy tissue. This focus is achieved by using a multi-leaf collimator, consisting of two rows of very thin tungsten alloy plates, which can be configured to exactly match the dimensions of the tumour.

Tungsten alloy is used as collimator 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 inspectionGamma
　
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 WOLFMET tungsten collimator is used to direct the radiation onto the target, whilst the radioactive source is housed inside tungsten shielding.

Homeland Security and Border Control
　
The penetrating power of radiation has also been put to use in the fight against terrorism. The Homeland Security industry has designed scanners that use gamma radiation to detect objects in cargo containers or airline baggage.
　
The radioactive sources are very strong and require WOLFMET tungsten shielding to protect security staff and members of the public from the radiation. A tungsten collimator is also required to direct the gamma radiation onto its target.

Tungsten alloy is used as Industrial radiography shielding in the following applications:

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.

The penetrating power of radiation has also been put to use in the fight against terrorism. The Homeland Security industry has designed scanners that use gamma radiation to detect objects in cargo containers or airline baggage.

The radioactive sources are very strong and require WOLFMET tungsten shielding to protect security staff and members of the public from the radiation. A tungsten collimator is also required to direct the gamma radiation onto its target.

Staff preparing and injecting radiopharmaceuticals in hospitals may receive significant radiation doses to their hands. These doses may be high enough to warrant that they be classified as radiation workers. The influence of local shielding on finger doses has been investigated. Staff preparing radioactive liquids in a radionuclide dispensary and drawing up and injecting radiopharmaceuticals in a nuclear medicine department have been studied.

The Tungsten Alloy Syringe Shield magnetically docks with the ChinaTungsten Dispensing Pig. Designed to accept 3cc, 5cc and 10cc B-D syringes, it places the needle inside the vial septum when engaged. The body of the shield is constructed of solid tungsten 2.1cm thick for maximum shielding. The external calibration rod allows the precise volume to be withdrawn without a leaded glass viewing port, where high exposure levels cannot be adequately shielded. The system allows the plunger to be pulled back with a pair of forceps, allowing you to keep your exposure as low as reasonably achievable.

Silicon carbide is composed of tetrahedra of carbon and silicon atomswith strong bonds in the crystal lattice. This produces a very hard andstrong material. Silicon carbide is not attacked by any acids oralkalis or molten salts up to 800°C. In air, SiC forms a protectivesilicon oxide coating at 1200°C and is able to be used up to 1600°C.The high thermal conductivity coupled with low thermal expansion andhigh strength give this material exceptional thermal shock resistantqualities.

Silicon carbide ceramics with little or no grain boundaryimpurities maintain their strength to very high temperatures,approaching 1600°C with no strength loss. Chemical purity, resistanceto chemical attack at temperature, and strength retention at hightemperatures has made this material very popular as wafer tray supportsand paddles in semiconductor furnaces. The electrical conduction of thematerial has lead to its use in resistance heating elements forelectric furnaces, and as a key component in thermistors (temperaturevariable resistors) and in varistors (voltage variable resistors).
