Weight reduction of aluminum cans has been achieved, year by year, by means of reducing can end diameter and improving shell form. This paper deals with the earing control technology of can body stock corresponding to reduction in can end diameter and the manufacturing technique of can end stock corresponding to new shell forms with a high buckle resistance. In terms of the body stock, we have improved our tandem hot finishing mill in the Fukui Works from the three-stand to the four-stand, in order to obtain a high orientation density of cube in the hot band, and have developed a low-earing can body stock using this hot rolling line. In terms of the can end stock, we have developed a high-formability can end stock by controlling the second phase particles and the final cold rolling reduction. Recently, weight reduction of cans and decreasing of can stocks thickness are apparently stagnated, but new type aluminum cans have begun to appear in the Japanese market attaching importance to environmental issues, re-seal function and design. So, it is anticipated that new characteristics will be needed for these cans.
