Sintered bearings can be considered P/M parts with a pore volume of between 17% and 30%. They are easily impregnated with lubricants or other substances, and are ideal for use as bearings with self–lubricating properties. They also are used as compound materials where the sintered alloys are compounded with a base material. The various alloy materials like sintered iron with graphite, copper, or lead additions, and sintered bronze with graphite and/or lead additions, have wide applications. With compound materials copper-tin alloys are widely used as the basic coating material and required properties are obtained by the addition of iron, lead, and graphite; steel plate usually serves as the base or backing material.
