We often use powder metallurgy technology for the production of new materials, then what is the characteristics of powder metallurgy?

First, the powder metallurgy technology can minimize the alloy composition segregation, eliminating the coarse and uneven casting organization. It has a very 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.

Followed by the preparation of amorphous, microcrystalline, quasicrystal, nanocrystalline and supersaturated solid solution and a series of high-performance non-equilibrium materials, these high-precision materials with excellent electrical, magnetic, optical and mechanical properties.

And then use the powder metallurgy technology can easily achieve a variety of types of composite, give full play to the characteristics of each group of source materials, can be said to be a low-cost production of high-performance metal-based and ceramic composite materials technology.

In addition, powder metallurgy technology can achieve near net shape and automated mass production, but also can effectively reduce the production of resources and energy consumption.

Finally, the use of powder metallurgy technology to make full use of ore, tailings, steelmaking sludge, rolling steel scales, recycling scrap metal as raw materials, is an effective material recycling and comprehensive utilization of new technologies.
