90WNiFe High Hardness Tungsten Alloy Pins With Wearing ResistanceTungsten 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. Introduction and Feature of Tungsten Alloy PinsTungsten 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.

Tungsten Alloy Pins Picture:
Application of Tungsten Alloy Pins- Tungsten Alloy Pins are made of high gravity tungsten
alloy. The wear resistance, hardness, strength and heat resistance
of the alloy are further improved, and the consistency of the
products is better ensured. Because of these characteristics,
tungsten iridium holes have become an important part of the
high-tech crystal glass industry.
