High Performance High Density Machined Heavy Tungsten Alloy Crucible

Heavy Tungsten Alloy Crucible is mainly divided into nickel-iron alloy, nickel-copper alloy, and even nickel-iron-copper alloy. 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 extended to various civilian industries.

What is Heavy Tungsten Alloy Crucible?

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 duty tungsten alloys are typically produced by mixing the desired tungsten, iron, nickel or copper powders, then cold pressing and liquid phase sintering until near full density. During the liquid phase treatment, the matrix tungsten alloy melts and part of the tungsten enters the solution, forming a microstructure of dispersed tungsten particles (20-60 μm).

Application of Heavy Tungsten Alloy Crucible

• Tungsten alloys have replaced lead in military products because their higher density allows them to retain their shape better, even under extreme conditions. Although uranium offers comparable density, its volatility and the special licensing requirements required for radioactive materials make processing difficult. Tungsten alloy is a kind of green environmental protection metal material, in the use and production process will not produce toxic substances. With the continuous expansion of military industry, the impact of military weapons on the environment should also be considered. The environmental performance of tungsten alloy makes it more and more prominent in the military field. Such as tungsten alloy tail shell piercing shells, tungsten alloy submarine weight, tungsten alloy engine accessories and so on.
