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.
