what is sintered copper used for
Composites of sintered materials based on copper with tin, lead (sometimes, zinc) and additives of nonmetallic components, usually silicon monoxide, have been used for friction wheels since 1932.n the mid-1930âs, mass production began of iron-and copper-base sintered materials in the form of precision parts not requiring further machining. The parts have been used in machine building, including the building of automotive vehicles, tractors, agricultural machinery, household appliances, and machine tools.
