        Tungsten alloy medical shielding products

        Technical details

        Tungsten alloy shielding is the first choice for radiation shielding. It can be used in both medical and industrial fields. Compared with traditional shielding materials (such as lead), tungsten alloy has better shielding performance. Due to the high density of tungsten alloy, its volume is 1 / 3 smaller than that of lead, but its shielding property is equivalent to that of lead. At present, people have made full use of the shielding properties of tungsten alloys, which are used in radioactive source containers, gamma ray and X-ray shielding parts. They can also be used as collimators and shielding parts in radiotherapy and syringe shielding parts.

        Tungsten alloy material has high density, high melting point, high hardness, high ultimate tensile strength, easy cutting, high elastic modulus, can effectively absorb X-ray and gamma ray (the absorption of X-ray and gamma ray is 30-40% higher than that of lead), non-toxic, pollution-free, corrosion resistance, good heat and conductivity characteristics. Therefore, it is widely used in the military field, such as the small arrow of cluster arrow, the "gunpowder cover" of shaped charge projectile, scattered ammunition, cluster ammunition, armor piercing projectile, etc., and has great lethality. In aerospace, missile and aviation industry, it is used for gyroscope components, missile guiding device, lift control and rudder balance device of aircraft and helicopter. In the field of sports goods, it is used for car crankshaft counterweight, golf head counterweight, tennis racket counterweight, dart pole, etc. Due to its high density and excellent radiation absorption ability, high specific gravity tungsten alloy is an excellent shielding material, which can be used as medical shielding tank, collimator, pet syringe, etc. With the increasing requirements of environmental protection, it has been widely used in the field of fish drop and gradually replaced the plumb.
