Basic Introduction of Metal powder

Metal powder is the basis for achieving large-scale production of non-standard metallurgical products. Metal powder refers to the metal particles with a size of less than 1mm, which is the main raw material for powder metallurgy. The small particle scale is in the range of 1nm-1mm, and 1nm is slightly equal to the length of 45 atomic arrangement. Metal powder is a loose substance, and its properties comprehensively reflect the nature of the metal itself and the characteristics of a single particle and the characteristics of granularity.

The performance of metal powder can generally be divided into chemical properties, physical properties and process performance. Chemical properties refer to the metal content and impurities. The more metal content, the higher the purity of the metal powder, and the better chemical properties; the physical properties include the average granularity and particle size distribution of the powder, the shape, surface shape, and internal shape of the particles, and the internal shape, and the internal appearance. The micro-structure, the thinner the particle size of the metal powder, the larger the surface area, the advantages of good sintering activity, high molding density, and low vortex loss, which will improve the mechanical performance of components. High-power electronics and power work scenarios are widely used; process performance is a comprehensive performance, including the fluidity of powder, loosening density, formability, and sintering dimensions. The performance of metal powder depends to a large extent on the production method and production process of powder.

Among them, the electronic high-end metal powder is different from the traditional metal powder industry. In order to meet the miniaturization and thinness of downstream electronic component products, the metal powder particle size is far less than the traditional powder metallurgical materials for electronic components. The production cost is far from ordinary powder metallurgical materials. According to the group classification, metal powder can be divided into single metal powder and alloy powder. Single metal powder is divided into iron powder, copper powder, aluminum powder, nickel powder, titanium powder, lead powder, tin powder, cobalt powder, chromium powder, silver powder, etc., which are widely used in powder metallurgy structure parts, diamond tools, magnetic materials, and magnetic materials, and magnetic materials, magnetic materials, and magnetic materials, and magnetic materials, and magnetic materials, and magnetic materials, and magnetic materials, and magnetic materials, and magnetic materials, and magnetic materials, and magnetic materials, magnetic materials, and magnetic materials. Fricate material batteries and other downstream areas. Alloy powder has iron -based alloy powder, nickel -based alloy powder, copper -based alloy powder, etc. Taking iron and silicon alloy powder as an example, iron and silicon powder have the characteristics of good spherical and high liquidity, and the corresponding prepared magnetic powder core has low power loss consumption, high DC superposition features and frequency and temperature stability are widely used in electric vehicle DC charging piles, solar photovoltaic inverters, high -power APFs with active filters and hybrid electrical resistors. In addition, metal powder can also be divided into electrolytic powder, reducing powder, atomized powder, cymbal powder, crushing powder, etc.; According to the application, it is divided into soft magnetic powder, high -temperature alloy powder, 3D printing special powder, electronic powder, etc. Contact us for free quote now!
