MANUFACTURE OF ALUMINUM ALLOY SHEET EXCELLENT IN CAN-OPENABILITY

PURPOSE:To remarkably improve the can-openability of aluminum alloy sheets, by refining crystalline grains after process annealing and also by making crystalline grains in sheet products nonelongated. CONSTITUTION:An aluminum alloy ingot has a composition consisting of, by weight, 2-3% Mg, 0.4-1% Fe...

Zusammenfassung:	PURPOSE:To remarkably improve the can-openability of aluminum alloy sheets, by refining crystalline grains after process annealing and also by making crystalline grains in sheet products nonelongated. CONSTITUTION:An aluminum alloy ingot has a composition consisting of, by weight, 2-3% Mg, 0.4-1% Fe, and the balance Al with inevitable impurities. This aluminum alloy ingot is subjected to homogenizing heat treatment at 450-550 deg.C, to rolling, and to annealing, followed by cold rolling at
