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.
