WHA (tungsten heavy alloy) weights for fixed and rotary wing aircraft have been used for many years.  WHA weights, unlike lead which creeps under its own weight at room temperature, can be securely fastened to aerostructures.  In contrast to DU weights, WHA weights are free from SCC concerns, special licensing requirements, environmental issues, and the negative public response to having many pounds of radioactive material routinely flying overhead.  

WHA weights are typically machined from near net shape blanks to precise tolerances and provided with a protective coating to the customer's specification.  This is an application where a coating is highly recommended to resist corrosion from temperature and moisture cycling, de-icing fluids, aggressive aircraft cleaning fluids, and galvanic contact with fasteners and the airframe.  Class 1 or 2 WHAs are most commonly used.

With rapid development of medical science, more and more radiation instruments are used in our lives. Medical instruments and nuclear power stations have become widespread and are now affecting all our lives. It is essential that people paid more attention to radiation and even more important for the institutions to protect public from the radiation exposure and to make sure to protect every radiation source of X-ray radiation, gamma radiation (energetic electromagnetic radiation), radiation of alpha particles (helium atoms) beta particles (electrons) and cosmic radiation, etc.

In order to protect patients and personnel from harmful effects of ionizing radiation, such as breast cancer, skin cancer, etc an excellent radiation-absorbing medium is badly needed. Tungsten alloy housing shielding is the material to be used for radiation shielding.

Tungsten alloy is ideal for tungsten alloy housing shielding against X-rays and gamma radiation. The very high density of tungsten alloy housing 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 tungsten alloy radiation shielding characteristics.

The density of tungsten cylinder is about 1.8 times than lead, which means that the tungsten is the size of lead about half of the same quality.

Pine car is so small, it is important to place the exact location, you need to determine its weight. Single tungsten cylinder at the top (0.5 oz) weight close to the bottom of the three zinc cyclinders (0.75 ounces) is the same as when your car is designed to give you more space, because you can be placed in a small area of ​​high weight, more precise with weights.

Tungsten heater filament is made of tungsten wire, featuring high melting point and high corrosion resistance, mainly application in vacuum metalized applicant, such as aluminizing scope, aluminum spraying, chrome scope, mirror making, ceramic coating, plastics and heater element for decoration articles.

Tungsten heater filament can be stranded into single or multi wires according to the samples or drawings of customers. Pure wire and doped wire are both available. Diameter of tungsten wire: 0.2-1.2mm.

Tungsten heater filament, single or multiple strand tungsten, molybdenum, or tantalum wire. Stranded wire can incorporate a core of aluminum for wetting purposes.
