Aluminum alloy plate

Abstract

The aluminum alloy plate of the present disclosure has the following components, that is, contains Si of 0.5% by mass or less; Fe of 0.7% by mass or less; Cu of 0.3% by mass or less; Mn of 0.4% by mass or more and 1.5% by mass or less; 0.7% by mass The above and 1.5% by mass of Mg; and the remainder, the remainder contains Al and unavoidable impurities. The concentration degree of the Goss orientation of the aluminum alloy plate is 1.5 or more. The aggregation degree of Cu orientation is 6.2 or less. The tensile strength is not less than 200 MPa and not more than 310 MPa. In addition, the area ratio of the α-Al-Fe-Mn-Si-based intermetallic compound having an equivalent circle diameter of 0.5 μm or more is preferably 2.6% or more.

Description

[0001] Cross References to Related Applications [0002] This international application claims priority from Japanese Invention Patent Application No. 2018-163486 filed at the Japan Patent Office on August 31, 2018, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to aluminum alloy plates. Background technique [0004] In late years we are selling bottle-shaped cans that are one type of aluminum cans. A bottle-shaped can has a body and a neck. The neck is thinner than the body. The bottle-shaped can has a threaded portion near the front end of the neck. The bottle-shaped can can be resealed by utilizing the screw part and the bottle cap. [0005] The bottle-shaped can was manufactured as follows. First, a round blank is drawn to form a cup. Then, the cup body is re-drawn using a can making machine. Next, shrink forming is performed successively with re-drawing forming to form the can body. [0...
