1A illustrates a clad configuration in accordance with a first embodiment of the disclosure. The custom alloy can also be designed to be compatible with conventional cladding processes and to be compatible with cosmetic alloys for the surface layer(s) in a clad configuration. The clad can be designed such that a property or properties of the substrate are within a range of properties of the surface layer.Ī custom alloy can be designed to incorporate high levels of UBC scrap. The substrate can include previously used aluminum, such as UBC scrap, that can increase the total amount of aluminum recycling. The surface layer can have various properties that provide cosmetic appeal. However, it is possible to clad a surface layer and a substrate, such as a substrate formed from a recycled material such as UBC scrap. The disclosure also relates to a clad including a recycled aluminum substrate and a surface layer.Īpple further notes that it is very difficult to make a cosmetic aluminum alloy from recycled material, such as UBC scrap. The first patent is titled 'Heat-Treatable Aluminum Alloy made from used Beverage can Scrap The second is titled 'Cosmetic Aluminum Alloys made from Recycled Aluminum Scrap.' While the aluminum that is used in MacBooks is derived from recycled aluminum pop and beer can scrap, the 'alloy' to create the MacBook actually contains other recycled metals as both patents describe.Īccording to Apple, the disclosure is directed to aluminum alloys that can incorporate used beverage can scrap. This past Thursday the US Patent & Trademark Office published two patent application from Apple relating to this topic of recycled aluminum. Below is the video of the Apple keynote that touched on this single point. This revelation was met with thunderous applause from the audience. In 2018 Apple revealed that the MacBook Air's enclosure was using 100% recycled aluminum.
