Characteristics of PM

PM has a unique chemical composition and mechanical, physical properties, and these properties are unable to be obtained by traditional casting methods. Using powder metallurgy technology can be made porous, semi-dense or fully dense material and products, such as oil bearing, gears, cams, guide rods, knives, etc. It is a small non-cutting process.

1.powder metallurgy technology can minimize the alloy component segregation, eliminating coarse and uneven casting organization. In preparation of high-performance permanent magnetic materials, rare earth hydrogen storage materials, rare earth luminescent materials, rare earth catalyst, high-temperature superconducting materials, new metal materials (such as Al-Li alloys, heat-resistant Al alloys, super alloys, corrosion resistant powder stainless steel, powder high-speed steel, inter-metallic compound high-temperature structural materials, etc.) powder metallurgy technology has an important role.

2.may be prepared in an amorphous, microcrystalline, quasi-crystals, nanocrystalline and supersaturated solid/solution etc. a series of high-performance non-equilibrium materials. These materials have excellent electrical, magnetic, optical and mechanical properties.

3.can easily achieve a variety of types of compound, give full play to the characteristics of each component material; it is a low-cost producing high-performance metal matrix composites and ceramic technology.

4.can produce special structure and properties materials and items that ordinary melting can not produce, such as new porous biomaterials, porous membrane materials, high-performance structural ceramics abrasive tools and functional ceramics materials.

5.can achieve near-net shape forming and automated mass production, which can effectively reduce production resources and energy consumption.

6.can take full advantage of ore, tailings, steel sludge, steel mill scale, recycling scrap metal as raw material; is a new technologies which can effectively carry out regeneration and comprehensive utilization of materials. The most common machining tools, hardware Abrasives, are mainly made by MIM manufacturing process.
