A method of continuous casting aluminum alloys between a pair of rolls. Molten aluminum alloy is delivered to a roll bite between the rolls and passes into the roll nip in a semi-molten state. A solid strip of cast aluminum alloy exits the nip at speeds of about 25 to about 400 feet per minute. Thin gauge (0.07-0.25 inch) strip may be produced at rates of up to 2000 pounds per hour per inch of cast strip width.
