A method of continuous casting non-ferrous alloys which includes delivering molten non-ferrous alloy to a casting apparatus. The casting apparatus rapidly cools at least a portion of the non-ferrous alloy at a rate of at least about 100&#xb0; C. thereby solidifying an outer layer of the non-ferrous alloy surrounding an inner layer of a molten component and a solid component of dendrites. The dendrites are altered to yield cast product exhibiting good resistance to cracking.

Casting of non-ferrous metals

A method of making aluminum alloy sheet in a continuous in-line process is provided. A continuously-cast aluminum alloy strip is optionally quenched, hot or warm rolled, annealed or heat-treated in-line, optionally quenched, and preferably coiled, with additional hot, warm or cold rolling steps as needed to reach the desired gauge. The process can be used to make aluminum alloy sheet of T or O temper having the desired properties, in a much shorter processing time.
