Heavy Tungsten Alloy Crucibles are made of tungsten base (tungsten content is generally 80%-98%) and a small amount of nickel, iron, copper, cobalt, molybdenum, chromium and other elements. The density of high specific gravity tungsten alloy can reach 15.20~18.70g/cm3, also known as high specific gravity tungsten alloy or high density alloy material. Because tungsten alloy weighs more than twice as much as steel.

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 light absorption capacity: 30-40% higher than general lead specific gravity, high thermal conductivity: mold It is 5 times that of steel; the thermal expansion coefficient is low: the capacity is only 1/2/3/3 of that of steel, with good electrical conductivity, good resistance to welding and cutting.
A common method of making heavy tungsten alloys is to mix the desired amount of tungsten, iron, nickel or copper powder and then cold-press liquid phase sintering to near full density. During the liquid phase treatment, the base tungsten alloy melts, and part of the tungsten enters the solution to form larger tungsten particles (20-60), which are dispersed in the base alloy with a μm structure.
