Tungsten-nickel-iron alloy is an alloy based on tungsten (about 90~98%) and adding nickel, iron, copper or other components, and its specific gravity is generally 17.0~18.5.
Proportion
Tungsten-nickel-iron alloy is an important tungsten-based heavy alloy. They are alloys made by adding nickel and iron to tungsten, and alloys that add other metal elements on this basis. The ratio of nickel to iron added is generally 7:3 or 1:1.
features
Tungsten-nickel-iron alloy is characterized by high sintering density, good strength and plasticity, and ferromagnetism. It has good plasticity and machinability, good thermal conductivity and electrical conductivity, and has good absorption capacity for γ-rays or X-rays.
Specific gravity: general specific gravity is 16.5-18.75g/cm3;
High strength: the tensile strength is 700-1000Mpa;
Strong ability to absorb rays: 30-40% higher than lead;
High thermal conductivity: the thermal conductivity of tungsten alloy is 5 times that of mold steel;
Small coefficient of thermal expansion: only 1/2-1/3 of iron or steel;
Good conductivity; because of its good conductivity, it is widely used in lighting and welding industries;
It has good weldability and processability.
use
Tungsten-nickel-iron alloy is widely used and has become the main tungsten-based heavy alloy with a large amount. For general applications, such as counterweights, counterweights, shielding devices, etc., sintered alloys are directly used; but for applications requiring high mechanical properties, tungsten-nickel-iron alloys require deformation processing and heat treatment to achieve strengthening.
Tungsten-nickel-iron alloy is mainly used in the manufacture of gyroscope rotors, guide devices and shock absorbers for aviation and spacecraft; die-casting molds, tool holders, boring bars and automatic watch hammers for mechanical manufacturing; bullet cores for conventional weapons, Rivet heads and switch contacts for electrical products; in addition, it is also used to manufacture various radiation-proof shielding components, etc.
