Tungsten Heavy Alloy Sheets Plate are kind of tungsten matrix (tungsten content is generally 80% - 98%) and contains a small amount of nickel, iron, copper, cobalt, molybdenum, chromium and other elements of the alloy material. The density of high specific gravity tungsten alloy is 15.20 ~ 18.70g/cm3, also known as high specific gravity tungsten alloy or high density alloy material. Because tungsten alloys weigh more than twice as much as steel.

The high specific gravity tungsten alloys are mainly divided into W-Ni-Fe, W-Ni-Cu and even W-Ni-Fe-Cu series. W-Ni-Fe alloy has good mechanical properties. The national defense industry and various fields of the national economy play a huge role. It is a very important new military material in national defense industry and is gradually popularized in various civil industries.
Tungsten alloy has a series of excellent characteristics, high specific gravity: general specific gravity of 16.5-18.75g/cm3, high strength: tensile strength of 700-1000mpa, strong light absorption capacity: 30-40% higher than its capacity lead, its thermal conductivity is 5 times that of die steel; Low thermal expansion coefficient: only 1/2-1/3 of steel, with good electrical conductivity; Good weldability and machinability.
Due to the high density of high specific gravity tungsten alloy, it has excellent ray absorption ability and is an excellent shielding material. For example, collimator, wing protection component and penumbra elimination block are made of high specific gravity tungsten alloy. The shielding part of the medical electronic linear belt loader also adopts high specific gravity tungsten alloy.
