Advantages and characteristics of powder metallurgy materials

Materials fabricated by the powder metallurgy method are referred to as powder metallurgy materials (MetallurgyMaterials Powder). The so-called powder metallurgy, is the production of powder and consolidation (such as compaction and sintering) powder to prepare materials or parts of the technical process. At present, it is an effective means to improve the performance of household electrical appliances and the development of new materials.

1.1 powder metallurgy is an effective way to make special functional materials

The special functional materials prepared by powder metallurgy can be classified into 5 categories:

1) can control the porosity (such as filter, oil bearing, etc.).

2) can produce fake alloy composite materials (such as contacts, metals, diamond, etc.).

3) can produce refractory metals (such as tungsten, molybdenum wire, etc.).

4) can produce components of homogeneous materials (such as dispersion strengthened copper, powder high speed steel, etc.).

5) can produce special functional materials (such as light, sound, electrical integration of materials, etc.).

Powder metallurgy is the technology of material and energy saving, environmental protection, powder metallurgy process almost does not produce soot or chemical contamination, the near net shape manufacturing parts and less or no cutting, least scrap losses, coupled with the single light weight material utilization rate is the highest. A powder metallurgy material is used for the statistics of the same products. The cost was reduced by 75%, efficiency increased by 1.7 times. Therefore, performance of household appliances materials to increase or reduce the cost of home appliances using wood from the point of view, development and application of powder metallurgy materials in the home appliance industry is imperative under the situation.
