ABSTRACT:
Compacted-particle sheets are wrought from essentially scrap aluminum. A relatively thick composite laminate of such sheets is then produced by preheating a plurality of compacted-particle sheets and bonding them together by hot rolling in a single pass through a hot rolling mill to achieve a thickness reduction of about 50 percent. A second pass through a rolling mill results in a further 20 percent reduction and improved bonding. Improved laminate qualities are also obtained by further laminating with other aluminum alloys and other metals.
