Process for forming an aluminum alloy strip, including the steps of a) obtaining an aluminum alloy consisting essentially of, by weight, 0.5 to 13% Si, 0 to 2% Mg, 0 to 2% Cu, 0 to 1% Mn, 0 to 2% Fe, other elements less than 0.5% each and less than 2% total, and remainder Al; and b) continuously casting the aluminum alloy between twin cooled rolls having a force applied thereto, to obtain a cast strip of thickness between 1.5 and 5 mm, and optionally cold rolling the cast strip. The force applied to the rolls is maintained below an amount represented by a straight line between a point A and a point B on a graph of specific applied force (y-axis) vs. cast width (x-axis), where point A is (1.5 mm, 750 tons/meter at cast width) and point B is (5 mm, 500 tons/meter of cast width).
