Abstract:
A method of making a rolled aluminum product comprises sawing an aluminum ingot so that the ingot is separated into at least two separate aluminum slabs and rolling at least one of the slabs unclad and unbrazed. In some embodiments, the ingot is sawn horizontally, across its face, as so that, the slabs are equal in length to the ingot. In some embodiments, at least one of the slabs is rolled to form a one of a plate, sheet or foil. The rolling can be hot rolling or cold rolling. Some embodiments further comprise scalping the aluminum ingot. In some embodiments, the sawing of the ingot eliminates or reduces the need to scalp the aluminum ingot and scalping is not performed. Some embodiments further comprise sawing curved edges off the aluminum slabs.
