ABSTRACT:
The present invention is a process to use aluminum alloy scrap to manufacture high quality machinable tooling plate. This is an new use for this scrap which has heretofore been used in lower quality products. The tooling plate thus made has superior properties when machined as it produces smaller chips and/or a limited of spirals from the plate. Large chips and long spirals create problems and a smaller chip greatly facilitates the machining operation.
