Title:
ALUMINUM ALLOY SHEET
Document Type and Number:
WIPO Patent Application WO/2020/045537
Kind Code:
A1
Abstract:
This aluminum alloy sheet has a composition including no more than 0.5% by mass of Si, no more than 0.7% by mass of Fe, no more than 0.3% by mass of Cu, 0.4% by mass to 1.5% by mass of Mn, and 0.7% by mass to 1.5% by mass of Mg, the remainder comprising Al and unavoidable impurities. The degree of integration in the Goss orientation is at least 1.5. The degree of integration in the Cu orientation is no greater than 6.2. The tensile strength is 200 MPa to 310 MPa. The area ratio of α-Al-Fe-Mn-Si-based intermetallic compounds having an equivalent circle diameter of at least 0.5 µm is preferably at least 2.6%.
