Powder metallurgy structural materials are divided into iron-based and copper-based materials according to different base metals. Iron-based materials are divided into sintered iron, sintered low-carbon steel, sintered medium-carbon steel and sintered high-carbon steel according to the amount of combined carbon. If the iron-based material contains alloy components copper and molybdenum, it is called sintered copper steel and sintered copper-molybdenum. steel. What is the difference between iron-based powder metallurgy materials and copper-based powder metallurgy materials?

Structural parts made of iron-based structural materials have high precision, small surface roughness, no or only a small amount of cutting, saving materials, high productivity, porous products, immersed in lubricating oil, and can reduce friction, vibration and noise. . Iron-based powder metallurgy structural materials are widely used in the manufacture of mechanical parts, such as adjusting washers, adjusting rings, end caps, sliders, bases, eccentrics on machine tools, oil pump gears, differential gears, thrust rings in automobiles, tractors On the transmission gear, piston ring and joints, spacers, nuts, oil pump rotors, blocking sleeves, rollers, etc.

Compared with iron-based structural materials, copper-based structural materials have lower tensile strength, higher plasticity and toughness, and have good electrical conductivity, thermal conductivity and corrosion resistance. , Instrument parts with high dimensional accuracy and less stress, as well as electrical and mechanical product parts, such as small module gears, cams, fasteners, valves, pins, sleeves and other structural parts.
