Polished Tungsten Heavy Alloy Plate
Polished Tungsten Heavy Alloy Plate is 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 Plate?
- Heavy tungsten alloy is a tungsten-based alloy material (tungsten content is generally 80%-98%), which contains a small amount of Ni, iron, copper, Co, Mo, Cr 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.
- A common method for preparing heavy tungsten alloys is to mix the desired tungsten powder, iron powder, nickel powder or copper powder, and then cold-press and liquid-phase sintering until near full density. During the liquid phase treatment, the matrix tungsten alloy melts, so that part of the tungsten enters the solution, forming a microstructure of dispersed tungsten particles (20-60 μm).
