What are the characteristics of copper-based powder metallurgy?
Copper-based powder metallurgy is a process technology for manufacturing metal powder or using metal powder as raw material, after forming and sintering, to manufacture metal materials, composite materials and various types of products. Powder metallurgy is similar to the production of ceramics, both belong to powder sintering technology, so a series of new powder metallurgy can also be used for the manufacture of ceramic materials. Due to the advantages of copper-based powder metallurgy, it has become the key to solving new material problems and plays an important role in the development of new materials.
Copper-based powder metallurgy contains powders and products. Where powder is primarily a metallurgical process, it is literally consistent. Powder metallurgy products are often far beyond the scope of materials and metallurgy, beyond the multi-disciplinary (materials and metallurgy, mechanical and mechanical, etc.) technology. In particular, modern metal powder 3D printing integrates mechanical engineering, CAD, reverse engineering technology, layered manufacturing technology, numerical control technology, material science, and laser technology, making powder metallurgy product technology a modern comprehensive technology that spans more disciplines.
What are the characteristics of copper-based powder metallurgy?
Copper-based powder metallurgy has unique chemical composition and mechanical and physical properties that cannot be obtained by traditional casting methods. Using powder metallurgy technology, porous, semi-dense or fully dense materials and products (such as planetary bearings, gears, cams, guide rails, tools, etc.) can be directly manufactured, which is a less cutting technology.
(1) Copper-based powder metallurgy technology can reduce the deviation of alloy composition and eliminate the coarse and uneven casting structure. For the 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, high temperature alloy, powder corrosion-resistant stainless steel, powder High-speed steel, intermetallic compound high-temperature structural materials, etc.) play an important role
(2) Copper-based powder metallurgy can prepare a series of high-performance unbalanced materials with excellent electrical, magnetic, optical and mechanical properties such as amorphous, microcrystalline, quasicrystalline, nanocrystalline, and supersaturated solid solutions.
(3) Copper-based powder metallurgy can easily realize various types of composite materials, give full play to the characteristics of raw materials of each group, and produce high-performance metal machine and ceramic composite materials at low cost.
(4) It can produce materials and products with special structures and properties that cannot be produced by ordinary smelting methods, such as new porous biological materials, porous separation membrane materials, high-performance structural ceramic abrasives, and functional ceramic materials.
(5) It can be formed almost smoothly and automated in mass production, effectively reducing the resource and energy consumption of production.
(6) New technologies that can be recycled as raw materials for ores, tailings, steelmaking sludge, rolled steel scales, and scrap metal.
Most of our common processing tools and hardware grinders are manufactured by copper-based powder metallurgy technology.
