Tungsten Heavy Alloy Nuts 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 gravity tungsten alloy is as high as 15.20~18.70g/cm3, also known as gravity tungsten alloy or high-density alloy material. Because tungsten alloy weighs more than twice as much as steel.

Tungsten Heavy Alloy Nuts Picture:
Tungsten alloy has a series of excellent properties, high specific gravity: general gravity lead 16.5-18.75g/cm3, high strength: tensile strength 700-1000mpa, strong light absorption capacity: 30-40% higher than general gravity lead, thermal conductivity: 5 times that of modulus steel; low thermal expansion coefficient: only 1/2-1/3 of carbon steel, good electrical conductivity, good welding and processing skills.
A common process for making heavy tungsten alloys involves mixing the desired amount of tungsten, iron, nickel or copper powder, followed by cold pressing and liquid phase sintering to near full density. During the liquid phase treatment, the matrix tungsten alloy melts and some tungsten enters the solution to form a microstructure, so that larger tungsten particles (20-60m) are dispersed in the matrix alloy.
