Powder metallurgy structure material

Powder metallurgy materials according to the different structure of base metal, divided into iron and copper based materials. Iron-based materials according to different combined carbon content of the iron sintering, sintering of low carbon steel, sintering carbon and sintering of high carbon steel, if the iron-based materials containing alloy element copper and molybdenum sintered steel and copper sintered copper molybdenum steel.

Iron base powder metallurgy structural materials made of structural parts, high precision, surface roughness value is small, do not need or only need a small amount of machining, material saving, high productivity, porous products, lubricating oil leaching, can reduce friction, damping, noise elimination. Powder metallurgy structural material widely used in the manufacture of mechanical parts, such as machine tool adjustment gasket, adjusting ring, an end cover, a slide block, a base, an eccentric wheel, auto oil pump gear, differential gear, check the push rings, tractor transmission gear, piston rings and the joint, a spacer sleeve, nuts, oil pump rotor, block sets, roller etc..

Compared with the copper based powder metallurgy material and structure of Fe based structural materials tensile strength low plasticity and toughness, has good electrical conductivity, thermal conductivity and corrosion resistance, various plating coating treatment, commonly used in manufacturing small and complex shape, size and high precision, small instrument parts and electrical appliances, mechanical product parts, such as small modulus gear, cam, fasteners, valve, a pin, a sleeve and structure.
