Tungsten Heavy Alloy Pins,
Tungsten Alloy Pins With Wearing Resistance,
90WNiFe Tungsten Alloy Pins
Tungsten Alloy Pins 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 the weight of tungsten alloy is more than twice that of 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, light absorption strength: 30-40% higher than general lead specific gravity, high thermal conductivity: the mold is 5 times that of steel; Low thermal expansion coefficient: the capacity is only 1 / 2 / 3 of that of steel, and the resistance to conduction, welding and cutting is good.
A common method for making heavy tungsten alloys is to mix the desired tungsten, iron, nickel or copper powders and then cold-press the liquid phase to near full density. During the liquid phase treatment, the base tungsten alloy is melted, and part of the tungsten enters the solution, forming a microstructure of large tungsten particles (20-60 m) dispersed in the base alloy.
