Abstract

High performance aluminum alloy products with desirable mechanical properties and methods for their preparation are provided herein. The high performance aluminum alloy products described herein contain a high content of recycled materials and are produced by casting an aluminum alloy to form a cast aluminum alloy product and processing the cast aluminum alloy product. The method of processing the cast aluminum alloy product may comprise two hot rolling steps.

Description

High-performance aluminum alloy with a large amount of recycled material and method of making the same CROSS-REFERENCE TO RELATED APPLICATIONS This application requires the rights and interests of U.S. Provisional Application No. 62 / 529,026 submitted on July 6, 2017, the U.S. The time application is incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates generally to metallurgy, and more particularly to the manufacture of aluminum alloys from recycled aluminum scrap. Background technique [0004] High performance aluminum alloys typically have very low impurity levels. Recycled materials may not be suitable for high performance Aluminum alloy, because the recycled aluminum alloy scrap contains a lot of impurities. SUMMARY OF THE INVENTION [0005] Embodiments encompassed by the present invention are defined by the claims, rather than by this summary of the invention. this hair This disclosure is a high-level overvie...
