Abstract: The present disclosure generally provides aluminum alloy products having a functional gradient across at least one dimension of the aluminum alloy product. The disclosure also provides articles of manufacture made from such products, and methods of making such products, such as through casting and rolling. The disclosure also provides various end uses of such products, such as in automotive, aerospace, marine, defense, transportation, electronics, and industrial applications.

Abstract: A bottom forming system for a metal container includes a domer assembly that forms a double dome in a bottom of the metal container during a bottom forming process. The domer assembly includes a first domer and a second domer that is movable relative to the first domer. A method of forming a bottom of a metal container includes forming a first dome profile in the bottom of the metal container using the first domer and the second domer of a domer assembly. The method includes forming a second dome profile in the bottom of the metal container by moving the second domer relative to the first domer.

Abstract: Provided herein are novel aluminum alloy compositions and methods of making and processing the same. The alloys described herein can be used in bottle making applications and exhibit enhanced runnability, formability, and appearance. The methods of producing an aluminum alloy sheet described herein can include casting an aluminum alloy to form an ingot, homogenizing the ingot, hot rolling the ingot to produce a hot band, and cold rolling the hot band to an aluminum alloy sheet of final gauge.

Abstract: A system for forming a score in a material includes an aluminum can and a tool. The aluminum can includes a can end, and an interior of the can end includes a coating. The tool includes a tool holder and a scoring knife. The scoring knife includes a proximal end configured to form the score in the can end. The proximal end has a width configured to minimize feathering of the coating when the score is punctured.
