What are the characteristics of copper-based powder metallurgy?


  copper-based powder metallurgyIt is a process technology for manufacturing metal powder or metal powder as raw material, forming and sintering, and manufacturing metal materials, composite materials and various types of products. Powder metallurgy method and the production of ceramics have similarities, belong to the powder sintering technology, so a series of new powder metallurgy technology can also be used in the manufacture of ceramic materials. Due to the advantages of copper-based powder metallurgy, it has become the key to solve the problem of new materials and plays an important role in the development of new materials.


Copper-based powder metallurgy contains powders and products. The powder is mainly a metallurgical process, which is literally consistent. Powder metallurgy products are often far beyond the scope of materials and metallurgy, beyond the multidisciplinary (materials and metallurgy, machinery and mechanics, etc.) technology. In particular, modern metal powder 3D printing integrates mechanical engineering, CAD, reverse engineering technology, layered manufacturing technology, numerical control technology, materials science, and laser technology, making powder metallurgy product technology a modern comprehensive technology that spans more disciplines.

Copper-based powder metallurgy has unique chemical composition and mechanical and physical properties, which 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, rails, tools, etc.) can be directly manufactured, which is a technology with less cutting.


(1) The copper-based powder metallurgy technology can reduce the bias of the alloy composition and eliminate the coarse uneven casting structure. It plays an important role in the preparation of high-performance rare earth permanent magnetic materials, rare earth hydrogen storage materials, rare earth luminescent materials, rare earth catalysts, high-temperature superconducting materials, new metal materials (such as Al-Li alloys, heat-resistant Al alloys, high-temperature alloys, powder corrosion-resistant stainless steel, powder high-speed steel, intermetallic compound high-temperature structural materials, etc.)


(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, quasicrystal, nanocrystal, and supersaturated solid solution.


(3) Copper-based powder metallurgy can easily realize various types of composite materials, and give full play to the characteristics of the raw materials of each group. It is a process technology for producing high-performance metal machines and ceramic composite materials at low cost.


(4) It can produce new porous biological materials, porous separation membrane materials, high-performance structural ceramic abrasives, functional ceramic materials and other materials and products with special structures and properties that cannot be produced by ordinary smelting methods.


(5) It can be almost smoothly formed and mass production automation, effectively reducing production resources and energy consumption.


(6) ore, tailings, steelmaking sludge, steel rolling scale, scrap metal can be recycled as raw materials of new technologies.


Most of our common processing tools and hardware grinding machines arecopper-based powder metallurgymanufactured by technology.
