Information

Iron-based powder metallurgy is a structural part manufactured by powder metallurgy process using iron powder or alloy steel powder as the main raw material. The requirements for such parts are to have sufficient mechanical properties, wear resistance, good machinability, and sometimes heat and corrosion resistance.

Features of Iron-based powder metallurgy:
1. The dimensional accuracy of the parts is high, and there is little and no cutting;
2. Porosity. Compared with dense metals, iron-based powder metallurgy structural parts have uniformly distributed pores. The uniformly distributed pores can remove the lubricating oil and improve the anti-friction property of the material, and the uniformly distributed spherical pores are also beneficial to the fatigue resistance of the parts under the condition of small energy and multiple impact. However, pores can reduce the mechanical properties of the material such as tensile strength, elongation after fracture and impact toughness, and affect the corrosion resistance, thermal conductivity, electrical conductivity and magnetic conductivity of the material. Iron-based powder metallurgy manufacturers tell you that according to the requirements of use, the pore size and pore distribution can be controlled by adjusting the material composition, particle size and process. But the smaller the pore size, the higher the manufacturing cost.
3. There is no segregation of alloy elements and the grains are fine and uniform. The alloying elements in iron-based structural materials are achieved by adding alloying element powders and mixing. Iron-based powder metallurgy manufacturers tell you that without smelting, the amount and type of alloying elements added are not limited by solubility and affected by density segregation, and segregation-free alloys and pseudo-alloys can be obtained. Pores hinder the growth of grains, so the grains of iron-based structural materials are finer.
