High Density W-Ni-Fe Alloy Plate

High density W-Ni-Fe alloy plate 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.

• Specific gravity: the general specific gravity is 16.5-18.75g/cm3;

•  High strength: tensile strength is 700-1000Mpa;

•  Strong ability to absorb rays: 30-40% higher than lead;

• Large thermal conductivity: the thermal conductivity of tungsten alloy is 5 times that of die steel;

• Small thermal expansion coefficient: only 1/2-1/3 of iron or steel;

• Good electrical conductivity; widely used in lighting and electric welding industries because of its good electrical conductivity;

• Has good weldability and processability;

• Magotan can produce high density W-Ni-Fe alloy plate of various shapes and sizes according to your requirements.

Mixing: mix tungsten powder, nickel powder, and iron powder (if the product has magnetic requirements, the copper powder can be added instead of iron powder and evenly mixed)

 High density W-Ni-Fe alloy plate 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; but for applications requiring high mechanical properties,  high density W-Ni-Fe alloy plate require deformation processing and heat treatment to achieve strengthening.

High density W-Ni-Fe alloy plate are 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 heavy hammers for machinery manufacturing; armor-piercing bullet cores for conventional weapons, rivet heads and switch contacts for electrical products; in addition, it is also used in the manufacture of various radiation-proof shielding components.
