   Powder metallurgy is a process technology for producing metal materials, composites, and various types of articles by forming or sintering metal or metal powder (or a mixture of metal powder and non-metal powder). Powder metallurgy has similarities to the production of ceramics. Therefore, a series of new powder metallurgy techniques can also be used for the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solving new material problems and plays a decisive role in the development of new materials.
Powder metallurgy has a unique chemical composition and mechanical and physical properties that are not available with conventional fusion casting methods. The use of powder metallurgy technology can directly produce porous, semi-dense or fully dense materials and products, such as oil-impregnated bearings, gears, cams, guides, tools, etc., is a less cutting process. The application and classification of powder metallurgy materials mainly include: powder metallurgy porous materials, powder metallurgy friction reducing materials, powder metallurgy friction materials, powder metallurgy structural parts, powder metallurgy mold materials, powder metallurgy electromagnetic materials and powder metallurgy high temperature materials.
  ( 1 ) Powder metallurgy technology can minimize the segregation of alloy composition and eliminate coarse and uneven casting structure. Preparation of high performance rare earth permanent magnet materials, rare earth hydrogen storage materials, rare earth luminescent materials, rare earth catalysts, high temperature superconducting materials, new metal materials (such as Al-Li alloy, heat resistant Al alloy, super alloy, powder corrosion resistant stainless steel, powder High-speed steel, high-temperature structural materials such as intermetallic compounds, etc.) play an important role.
  ( 2 ) A series of high-performance non-equilibrium materials such as amorphous, microcrystalline, quasicrystal, nanocrystalline and supersaturated solid solution can be prepared, which have excellent electrical, magnetic, optical and mechanical properties.
  ( 3 ) It is easy to realize various types of recombination, give full play to the respective characteristics of each component material, and is a process technology for producing high-performance metal-based and ceramic composite materials at low cost.
  ( 4 ) It can produce materials and products with special structure and properties that cannot be produced by ordinary smelting methods, such as new porous biomaterials, porous separation membrane materials, high performance structural ceramics and functional ceramic materials. Welcome to the company's official website http://
  ( 5 ) It can realize net near formation and automatic mass production, thereby effectively reducing production resources and energy consumption.
  ( 6 ) It can make full use of ore, tailings, steelmaking sludge, rolling steel scales, and recycling used metal as raw materials. It is a new technology that can effectively carry out material regeneration and comprehensive utilization.
 Many of our common machining tools are made by powder metallurgy.
