Tungsten Alloy Bolts High Temperature Resistance
Tungsten Heavy Alloy Bolts 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 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, and thermal conductivity: 5 times of modulus steel; Low thermal expansion coefficient: only 1 / 2-1 / 3 of carbon steel, good conductivity and good welding processing skills.
A common method of making heavy tungsten alloys is to mix the desired amount of tungsten, iron, nickel or copper powder, then cold-press and liquid-phase sinter to near full density. During the liquid phase treatment, the matrix tungsten alloy is melted, and part of the tungsten enters the solution to form a microstructure, so that larger tungsten particles (20-60m) are dispersed in the matrix alloy.
