Tungsten Nickel Iron (W-Ni-Fe) High Density Alloy Machined Parts

Tungsten Nickel Iron (W-Ni-Fe) High Density Alloy are alloys composed of tungsten and other elements. Among metals, tungsten has the highest melting point, good high temperature strength and creep resistance, as well as thermal conductivity, electrical conductivity and electron emission properties. A heavy alloy is a sintered material that increases density by adding metals such as nickel, copper and iron to tungsten. Due to its excellent mechanical properties, such as high density, high vibration damping properties, and high Young's modulus, as well as excellent radiation shielding and heat resistance, it has been used in a wide range of fields.

Introduction and characteristics of Tungsten Heavy Alloy Part

1. The tungsten content of heavy tungsten alloys is 90% to 98%, which is responsible for their higher density (16.5 to 19.00g/cc). Nickel, iron and/or copper are used as metal adhesive substrates to hold the brittle tungsten particles together, making the tungsten alloy malleable and easy to work. Ferric nickel-nickel is the most commonly used additive with a ratio of 7Ni: 3Fe or 8Ni: 2Fe (by weight).
2. A common method of preparing heavy tungsten alloys is to mix the desired amount of tungsten, iron, nickel or copper powder and then perform cold pressing and liquid phase sintering to near full density. During the liquid phase treatment, the base tungsten alloy melts and causes some tungsten to enter the solution, forming a microstructure through which large tungsten particles (20-60μm) are dispersed in the base alloy.

Application of Tungsten Heavy Alloy Part

• Thermoelectric generator is a fusion power device that uses radioactive isotopes. It can use high-density tungsten alloys as containers. Widely used in weather stations, light buoys, acoustic communication beacons, ocean research and other fields.
