Development of a Castable High Strength Secondary Aluminum Alloy from Recycled Wrought Aluminum Scrap

This project lays out an approach to develop a new process for recycling aerospace (AA7075) aluminum scrap into a high strength castable aluminum alloy. The project will focus on developing approaches to overcome the technical challenges (such as hot tearing and macrosegregation) which limit industry’s ability to process and use up to 35,000 metric tons of aluminum scrap. The expected energy benefits are estimated at 6.5 PJ per year with an emissions reduction of about 370,000 metric tons per year.
