What is Tungsten Nickel Iron W-Ni-Fe Alloy?
Tungsten nickel-iron alloy is a tungsten-based (about 90%-98%) and adding nickel, iron, copper components of the alloy, the specific gravity is generally 17.0-18.5, with high sintering density, strength and plasticity are good, there are certain ferromagnetic characteristics. It is widely used in radiation protection and guidance, industrial counterweight parts, security and defense parts, etc.
What are Tungsten Nickel Iron Alloy properties?
The properties of tungsten-nickel-iron alloy are as follows:
- Specific weight: density about 18.8g/cm³;
- High strength: tensile strength of 700-1000Mpa;
- Strong ray shielding ability: under the same thickness conditions, tungsten alloy ray shielding ability is 1.7 times more than lead, when the stronger the ray, the more obvious the difference between the two ray shielding ability;
- High thermal conductivity: the thermal conductivity of tungsten alloy is 5 times that of die steel;
- Small coefficient of thermal expansion: the coefficient of thermal expansion of tungsten is 4-6×10⁻⁶/℃, only 1/2-1/3 of iron or steel;
- Good shape, workability and weldability.
What's the application of Tungsten nickel Iron Alloy?
Tungsten-nickel-iron alloy is an important tungsten-based heavy alloy, its application areas include:
- Aerospace: Used in the manufacture of gyroscope rotors, guidance devices and shock absorbers.
- Mechanical manufacturing: for the manufacture of die casting die, tool holder, boring bar and automatic watch weight.
- Conventional weapons: used to make armor-piercing cartridges.
- Electrical products: For the manufacture of rivets and switch contacts.
- Anti-radiation shielding parts: used to manufacture various anti-radiation shielding parts.
In addition, tungsten nickel alloy can also be used in the manufacture of nuclear power and energy components, industrial counterweight components, security and defense parts.
