How to produce spherical tungsten nickel iron alloy powder?

Spherical tungsten-nickel-iron alloy powder can be produced by a variety of methods, and the common ones are mechanical alloying method, sol-gel method, high-temperature reduction method, and so on.

The mechanical alloying method is prepared by mixing, crushing, and sintering tungsten, nickel, iron, and other raw materials in a series of processes through a high-energy ball mill. The powder particles prepared by this method are uniform in shape, narrow in size distribution, and smooth in surface, with high specific surface area and activity, which are suitable for preparing high-performance catalysts and electrode materials.

The sol-gel method is to take metal salt as raw material, prepare the precursor of metal oxides through chemical reaction, and then reduce the precursor at high temperature to get metal monomers. The tungsten-nickel-iron alloy powder prepared by this method is uniform in size and narrow in particle size distribution, but the production cost is higher.

The high-temperature reduction method reduces metal oxides or sulfides at high temperatures to get metal monomers. The tungsten-nickel-iron alloy powder prepared by this method has high purity and low impurity content, but the production process needs to consume a lot of energy and time.

What is the application of spherical tungsten nickel iron alloy powder?

Spherical tungsten-nickel-iron alloy powder is widely used in aerospace, aviation, navigation, military, national defense, automotive, chemical industry, and other fields.

In the electronics industry, spherical tungsten-nickel-iron alloy powder has good electrical conductivity and thermal stability and is often used to prepare electrical contact materials for electronic devices. As a raw material for electrical contact materials, it can provide good electrical conductivity and stability, which makes electronic devices have better performance.

In addition, spherical tungsten-nickel-iron alloy powder plays an important role in preparing metal-ceramic materials. Metal-ceramic material is a composite material composed of metal and ceramic phases, which has the toughness of metal and the hardness of ceramic. Spherical tungsten-nickel-iron alloy powder, as a raw material for metal-ceramic materials, can provide a good combination between the metal phase and the ceramic phase, which makes the metal-ceramic materials have better mechanical properties and wear-resistant properties.
