Title:
ALUMINUM ALLOY PLATE FOR CAN BODY AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2014/129385
Kind Code:
A1
Abstract:
Provided is an aluminum alloy plate for a can body having a chemical composition that includes, in mass%, 1.0-1.5% of Mg, 0.8-1.2% of Mn, 0.20-0.30% of Cu, 0.25-0.60% of Fe, 0.20-0.40% of Si, and a remainder of Al and unavoidable impurities, and that has a conductivity of 37.0-40.0% IACS. The aluminum alloy plate for a can body is produced through a plurality of cold-rolling passes, and the tensile strength σB(10) and yield strength σ0.2(10) when the material is aged for ten hours at a temperature of 150 °C directly before the final cold-rolling pass and the tensile strength σB(1) and yield strength σ0.2(1) when the material is aged for one hour at a temperature of 150 °C directly before the final cold-rolling pass satisfy the relationships σB(10) - σB(1) ≥ 5 (Mpa) and σ0.2(10) - σ0.2(1) ≥ 1 (Mpa).
