Product Description
Tungsten Alloy Shafts with tungsten as the matrix (tungsten content is generally 80%~98%), add a small amount of nickel, iron, copper, cobalt, molybdenum, chromium and other elements. High density tungsten alloy density as high as 15.20~18.70g/cm3, also known as high proportion tungsten alloy or high density alloy material. Because the tungsten alloy weighs more than twice as much as the steel.

Tungsten Alloy Shafts Picture:
Tungsten alloy has a series of excellent properties, high specific gravity: General specific gravity 16.5-18.75g/cm3, high strength: tensile strength 700-1000mpa, strong ray absorption capacity: its capacity is 30-40% higher than that of lead with general specific gravity, and its thermal conductivity is 5 times that of die steel; Small thermal expansion coefficient: only 1 / 2-1 / 3 of steel, good conductivity; Good weldability and machinability.
A common process for preparing tungsten alloys includes mixing the required tungsten, iron, nickel or copper powders, and then cold pressing and liquid phase sintering until the density is close to full. During the liquid phase treatment, the base tungsten alloy melts and brings part of tungsten into the solution to form large tungsten particles (20 ~ 60 μ m) Dispersed in the matrix alloy.
