About Metal Alloy 17g/cm3 Tungsten Nickel Iron Bar Tungsten Alloy Bar:
Tungsten nickel-iron (W-Ni Fe) alloy is also a three-phase alloy, an alloy material based on the refractory metal tungsten.
Tungsten nickel-iron alloy is a tungsten-based alloy with tungsten as the hard phase and nickel and iron as the bonding phase. Its English name is Ferro tungsten nickel alloy, with a nickel-iron ratio of 7:3 or 1:1 and a tungsten content of 90% to 98%.

The characteristics of tungsten nickel iron alloy include high specific gravity (16.5-18.75g/cm3), high strength (tensile strength 700-1000Mpa), and strong ability to absorb radiation (30-40% higher than lead under the same thickness); High thermal conductivity (5 times that of mold steel); Low coefficient of thermal expansion (approximately 1/2-1/3 of iron or steel); Good conductivity, plasticity, thermal conductivity, weldability, and processability; Has a certain degree of ferromagnetism.

Tungsten-nickel-iron alloy has high sintering density, strength and plasticity, and certain ferromagnetism. It has good plasticity and machinability, good thermal and electrical conductivity, and excellent absorption capacity for γ-ray or X-ray.



Low thermal expansion, high density, radiation absorption, high thermal and electrical conductivity, wear resistance, perfect performance in high radiation exposure environment.



Tungsten-nickel-iron alloy is widely used and has become the main tungsten-based heavy alloy with the largest amount. For general applications, such as counterweights, counterweights, radiation shielding devices, etc., sintered alloys are directly used. Still, for applications requiring high mechanical properties, tungsten-nickel-iron alloys require deformation processing and heat treatment to achieve strengthening.

1. Tungsten-nickel-iron alloys are mainly used in the manufacture of gyroscope rotors, guide devices, and spacecraft;

2. Die-casting molds, tool holders, boring bars, and automatic watch weights for machinery manufacturing;

3. Armor-piercing bullet cores for conventional weapons, rivet heads, and switch contacts for electrical products;

4. It is also used to manufacture various radiation shielding components.
