High Performance Machined Tungsten Heavy Alloy Tools For Industrial Use

Tungsten Heavy Alloy Tools 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.

What is Tungsten Heavy Alloy Tools?

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 of making heavy tungsten alloys is to mix the desired tungsten, iron, nickel or copper powders, then cold-press and liquid-phase sinter 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 a dispersed tungsten particle (20~60μm) structure.

Application of Tungsten Heavy Alloy Tools

• Tungsten alloys with high specific gravity are used to make tool holders, especially boring bars.

• The high specific gravity tungsten alloy is used as the counterweight material for the high crankshaft of the small engine of the chain saw for the monthly supply of forest.

• Electrodes of EDM and electrochemical machine tools are also made of tungsten with high specific gravity
