Abstract
Techniques are disclosed for casting high-strength and highly formable metal products from recycled metal scrap without the addition of substantial or any amounts of primary aluminum. Additional alloying elements, such as magnesium, can be added to metal scrap, which can be cast and processed to produce a desirable metal coil at final gauge having desirable metallurgical and mechanical properties, such as high strength and formability. Thus, inexpensive and recycled metal scrap can be efficiently repurposed for new applications, such as automotive applications and beverage can stock.
