High Density Heavy Tungsten Alloy Bolts For Industry WNiFe

Heavy Tungsten Alloy Bolts is also known as tungsten heavy alloy, because the tungsten alloy weighs more than twice as much as iron or steel.High-specific gravity tungsten alloys are usually a refractory metal composed of W-Ni-Fe or W-Ni-Cu or even W-Ni-Cu-fe two-phase composites.Some tungsten alloys added with rare earth and / or other metals, such as cobalt, molybdenum, chromium and heavy tungsten alloys, have a high melting point, are twice the density of steel, and are more than 50% heavier than lead.

Introduction and characteristics of Heavy Tungsten Alloy Bolts

1. Heavy tungsten alloy content is between 90% and 98%, which is the reason for its high density (16.5 ~ 19.00g / CC).Nickel, iron, and / or copper are used as metal bonding substrates to fix fragile tungsten particles, which makes the tungsten alloy malleable and easy to process.Iron and nickel is the most commonly used additive with a ratio of 7Ni: 3Fe or 8ni: 2Fe (weight ratio).
2. Common processes used for preparing heavy tungsten alloys include mixing the desired amounts of tungsten, iron, nickel or copper powder followed by cold pressure and liquid phase sintering to almost complete density.During the liquid phase treatment, part of the matrix tungsten alloy melt brings the tungsten into the solution to form a microstructure, and the larger tungsten particles (20 ~ 60 m) are dispersed in the matrix alloy.

Application of Heavy Tungsten Alloy Bolts

• Therthermogenerator is a device that produces fusion energy by using radioactive isotopes.It can use a high-density tungsten alloy as a container.It has been widely used in weather stations, light buoys, acoustic communication beacons, ocean research and other fields.
