Product Description

90WNiFe High Hardness Tungsten Alloy Pins With Wearing Resistance

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.

 

Introduction and Feature of Tungsten Alloy Pins

  1. 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.

  2. 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.

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.
