Six advantages of powder metallurgy technology


Powder metallurgy is a kind of technology that produces metal or uses metal powder (or the mixture of metal powder and nonmetal powder) as raw materials, with which produces metal materials, composite and other various types of products after forming and sintering. In view of currently application of powder metallurgy technology, it has following advantages:

a. Powder metallurgy technology can minimize the segregation of alloy composition as well as eliminate thick and uneven casting structure.

It will have great effect on producing high performance rare earth permanent magnet materials, rare earth hydrogen storage materials, rare earth luminescent materials, rare earth catalysts, high-temperature superconducting materials and new metallic materials (such as Al-Li alloy, heat-resistant Al alloy, superalloy, wear resistance stainless steel powder, high speed steel and intermetallic high temperature structural materials, etc).

b. It can produce amorphous, microcrystal, quasicrystal, nanocrystalline, super saturation solid solution and other high performance nonequilibrium materials that have excellent electricity, magnetics, optics and mechanical properties.

c. By using this technology, different types of materials can be easy to composite and the characteristics of every component material can be made full use, which is a kind of technology that produces high performance metal base and ceramic composite materials with low cost.

d. It can produce materials and products that have special structure and performances which cannot be produced by normal smelting process, such as new type of porous biological materials, porous membrane materials, high performance structural ceramics and functional ceramic materials, etc.

e. It can realize near net forming and automation batch production, thus it can effectively reduce the production resources and energy consumption.

f. By using this technology, ores, gangues, steelmaking mud, roll steel and iron scale as well as recycled scrap metal can be made full use and served as the raw materials, which is a kind of new technology that can effectively regenerate and comprehensively utilize materials.
