Market Conditions And Production Processes Of Atomized Nickel Powder

Atomization nickel powders raw material is pure nickel

. It is prepared though the atomization method. Atomized nickel powder is light gray or dark gray. Because of its irregularly shaped features, it is mainly used in special electrode, surface coating, heavy alloy, diamond drill and powder metallurgy parts.

In recent years, with the continuous development of the atomic energy industry, batteries, electrical alloys, high temperature and high strength alloys, machinery, automobile manufacturing, diamond tools and stone, metal parts and other areas of the atomization of nickel powder consumption increasing applications more and more widely, the development and application and has broad prospects. Because atomization legal system powder with low energy consumption, no pollution, only a small amount of the production process wastes generated, etc., will be the main method of milling.

The atomized nickel powder is a metal powder occupies a more important position in powder metallurgy industry. It can be used in producing a variety of mechanical components and related materials can also be directly applied to a number of occasions, such as metal powder additives, welding rod, coating coatings. Nickel-based alloy powder and cobalt-based alloy powder, such as for a stiff dough technology, self-fluxing alloy powder and heat-resistant, wear-resistant, corrosion resistant alloy powder, etc. using the atomization method of production of nitrogen and water as the medium. The use of aviation, aerospace nickel base, cobalt-based high temperature alloy powder mainly used for production of vacuum melting of argon gas atomization method.

Manufacture of porous filter elements, dense profiles of nickel material, the powder metallurgy structural components and its alloying elements additives, is also inseparable from the atomization production of nickel powder and nickel-based alloy powder. Welding can be used as the electrode, the flux in the alloy composition. Charge as Tim in the brazing metal. Atomization of nickel powder in powder metallurgy parts, stiff dough spraying, welding, special welding rod, the porous filter element. From the production and application on the market is in the developmental stage and with the growing market demand and technological development, the diverse needs a variety of nickel powder and copper powder.

There are two production processes of water atomization and gas atomization in production of atomized nickel powder. There are electrolytic nickel melting, atomization, dry filter, restore and screening co-approved packaging processes. The essential difference between the two processes is different medium in atomization. Production method largely depends on the required powder properties. One metal powder exporter claims that shape of aerosol powder is spherical or nearly spherical. The oxygen content of powder is high. If the powder is prepared by inert gas atomization, there is low oxygen content in powder. The shape of water atomized powder is generally irregular. And its oxygen content is between aerosolization and protective gas atomization. For powder production with big output and low cost, water atomization is usually better than gas atomization.
