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.

Abstract: Disclosed herein are methods of processing 7xxx aluminum alloys using a rapid pre-aging step, along with alloys prepared according to the methods. The aluminum alloy products described herein have high strength when subjected to a rapid pre-aging step, as described above, and subsequent thermal treatment, such as paint baking or coating. The alloys prepared and processed according to the methods described herein can be used, for example, in automotive, transportation, electronics, and industrial applications.

Abstract: A continuous casting and rolling line for casting, rolling, and otherwise preparing metal strip can produce distributable metal strip without requiring cold rolling or the use of a solution heat treatment line. A metal strip can be continuously cast from a continuous casting device and coiled into a metal coil, optionally after being subjected to post-casting quenching. This intermediate coil can be stored until ready for hot rolling. The as-cast metal strip can undergo reheating prior to hot rolling, either during coil storage or immediately prior to hot rolling. The heated metal strip can be cooled to a rolling temperature and hot rolled through one or more roll stands. The rolled metal strip can optionally be reheated and quenched prior to coiling for delivery. This final coiled metal strip can be of the desired gauge and have the desired physical characteristics for distribution to a manufacturing facility.

Abstract: Described herein are 7xxx series aluminum alloys with unexpected properties and novel methods of producing such aluminum alloys.

The alloys can be used in automotive, transportation, industrial, and electronics applications, just to name a few.

Abstract: A rotating magnet heater for metal products, such as aluminum strip, can include permanent magnet rotors arranged above and below a moving metal strip to induce moving or time varying magnetic fields through the metal strip. The changing magnetic fields can create currents (e.g., eddy currents) within the metal strip, thus heating the metal strip. A magnetic rotor set can include a pair of matched magnetic rotors on opposite sides of a metal strip that rotate at the same speed. Each magnetic rotor of a set can be positioned equidistance from the metal strip to avoid pulling the metal strip away from the passline. A downstream magnetic rotor set can be used in close proximity to an upstream magnetic rotor set to offset tension induced by the upstream magnetic rotor set.
