Recycling aluminum alloys has been shown to provide major economic benefits. As a result, it is appropriate for the aluminum industry and the U.S. as a whole to identify, develop, and implement all technologies that will optimize the benefits of recycling. This paper will focus primarily on alloy design for optimizing the reuse of recycled metal; this is both the most forward looking area as we move toward a more recycle-friendly world, and the most overlooked for its potential in maximizing the recycle loop. Some specific approaches to alloy design for recycling are put forth, and some specific compositions for evaluation are proposed. Options for moving forward to further capitalize on the advantages of aluminum recycling are also addressed.
