High Performance 90WNiFe Machined Tungsten Heavy Alloy Crucibles

Tungsten Heavy Alloy Crucibles are mainly divided into nickel-iron alloys, nickel-copper alloys, and even nickel-iron-copper alloys. In contrast, wide nickel-iron alloys have better mechanical properties and play an important role in the defense industry and various fields of the national economy. It is a very important new material in the defense industry and is gradually expanding to various civilian industries.

Chemical composition of Tungsten Heavy Alloy Crucibles

What is Tungsten Heavy Alloy Crucibles?

1. Heavy tungsten alloy is a tungsten-based alloy material (tungsten content is generally 80%-98%), which contains 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 tungsten weighs more than twice as much as alloy steel.

2. Heavy tungsten alloys are usually prepared by mixing the desired tungsten, iron, nickel or copper powders, then cold pressing and liquid phase sintering until they are close to full density. During the liquid phase treatment, the matrix tungsten alloy melts and part of the tungsten enters the solution to form dispersed tungsten particles (20~60μm).

Application of Tungsten Heavy Alloy Crucibles

• Tungsten alloys have replaced lead in military products because their density better holds their shape, even under extreme conditions. Although uranium is highly dense, its volatility and special permit requirements for radioactive materials make processing difficult. Tungsten alloy is a green metal material that does not produce toxic substances during use and production.

• As the military industry continues to grow, we should also consider the environmental impact of military weapons. The environmental performance of tungsten alloy makes its application in the military field more and more prominent. Such as tungsten alloy tail shell perforated shell, tungsten alloy potential weight, tungsten alloy engine accessories, etc.
