Characteristics of copper based powder metallurgy

Copper based powder is frequently used in the process of powder metallurgy. As one of the raw materials of powder metallurgy, it is very common. What are the characteristics of copper based powder metallurgy

powder metallurgy

Copper based powder metallurgy is a process technology to make metal or metal powder as raw material, through forming and sintering, to manufacture metal materials, composites and various types of products. Powder metallurgy is similar to the production of ceramics. Therefore, a series of new copper based powder metallurgy technologies can also be used to prepare ceramic materials. Due to the advantages of powder metallurgy technology, it is the key to solve the problem of new materials and plays a decisive role in the development of new materials.

(1) Copper based powder metallurgy technology can minimize the segregation of alloy components, eliminate coarse and uneven casting structure, and prepare 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 alloy, heat-resistant Al alloy, superalloy, powder corrosion resistant stainless steel, powder high-speed steel, intermetallic compound high-temperature structural materials, etc.) play an important role

(2) A series of high-performance non-equilibrium materials such as amorphous, microcrystalline, quasicrystalline, nanocrystalline and supersaturated solid solution can be prepared. These materials have excellent electrical, magnetic, optical and mechanical properties.

(3) It can make full use of ores, tailings, steelmaking sludge, steel mill scale, and recycled waste metals as raw materials. It is a new technology that can effectively regenerate and comprehensively utilize materials.

(4) Various types of composites can be easily realized, giving full play to the respective characteristics of each component material. It is a low-cost technology to produce high-performance metal matrix and ceramic composites.

(5) It can produce materials and products with special structures 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 ceramics.

(6) It can realize net near formation and automatic batch production, thereby effectively reducing production resources and energy consumption.

In a word, copper based powder metallurgy not only has excellent performance, but also is easy to prepare and use. It is also widely used in powder metallurgy technology.
