High Density W-Ni-Fe Alloy Bar

Tungsten-nickel-iron alloy is an important tungsten-based heavy alloy. These are alloys formed by adding nickel and iron to tungsten, and alloys with other metal elements are added on this basis. The ratio of nickel to iron added is generally 7:3 or 1:1.

Product Introduction

High density W-Ni-Fe alloy bar

High specific gravity tungsten alloy is an alloy material, also known as high-density tungsten alloy or heavy alloy, which is made of tungsten as the matrix material (containing 85%~99% tungsten) and a small amount of nickel (Ni), copper (Cu), iron (Fe), cobalt (Co), molybdenum (Mo), chromium (Cr) and other metal bonding agents. The density of high specific gravity tungsten alloy can reach 16.5~19.0g/cm^3. More commonly used are W-Ni-Cu and W-Ni-Fe two series. High density W-Ni-Fe alloy bar has remarkable characteristics in density, strength, hardness, ductility, electrical/thermal properties, and other physical properties, so it has been widely used in the defense industry, aerospace industry, medical industry, electrical industry, and other industries.
