Abstract
Strip casting of A6061 alloy was tried using a vertical type twin roll caster with 1500mm of diameter rolls. Use of copper rolls, non-use of lubricant, and low load contributed to improve the cooling rate and casting speed of the strip. A6061 alloy could be cast into the strip continuously at the speed of 60m/min. The microstructure was very fine. It's could be cold-rolled without homogenization to 1mm. A6061 strip could be bent 180 degrees without occurrence of crack at the outer surface or breaking.
