Abstract
An orbiting scroll is made with a ceramic particle reinforced aluminum metal matrix composite. The resultant part has increased wear resistance, closer thermal expansion matching with cast iron, can be used without tip seals and offers the advantages associated with a reduced mass. In manufacturing the part, the part is pressure cast to a near net shape and machined to the final shape.
