Embodiment Construction
[0017] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0018] A high-performance powder metallurgy material is composed of iron powder, aluminum powder, ferrochrome, zinc stearate and graphite powder. Wherein the main components are iron powder and aluminum powder, and the percentage by weight between the iron powder and aluminum powder is 80-70% of iron powder and 20-30% of aluminum powder. Adding Al to the main component improves the performance of the powder metallurgy material, and its indoor bending strength can reach 2500MPa, and the relative density is greater than 99.9%.
[0019] The powder metallurgy material also includes 0.5-2% by weight of ferrochrome, 0.08-0.5% of ...
