Heavy tungsten alloy sheet is based on tungsten (tungsten content is generally 80% ~ 98%) with 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 iron or steel.

Heavy Tungsten Alloy Sheet Picture:
The high specific gravity tungsten alloys are mainly divided into two series: W-Ni-Fe and W-Ni-Cu, and even W-Ni-Fe-Cu. In contrast, W-Ni-Fe alloy has better mechanical properties. The defense industry and all areas of the national economy play a huge role. It is a very important new military material in the national defense industry and is gradually being popularized in various civil industries.
Tungsten heavy 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 ray absorption capacity: its capacity is 30-40% higher than lead, large thermal conductivity: 5 times of die steel; Low thermal expansion coefficient: only 1/2-1/3 of steel, good electrical conductivity; Good weldability and machinability.
