High Performance Machined Tungsten Heavy Alloy Parts

Tungsten Heavy Alloy Parts 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 extended to various civilian industries.

What is Tungsten Heavy Alloy Parts?

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. A common method for making heavy tungsten alloys is to mix the desired tungsten, iron, nickel or copper powders, then cold-press 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).
