Inventor(s) include Nakamura Shinichi; Totani Yuki; and Doko Takeyoshi.
The application for the patent was published on Oct. 10, under issue no. 41/2025.
According to the abstract released by the Intellectual Property India: "Disclosed is an aluminum alloy sheet which has a thermal bonding function as a single layer, and which is characterized by being formed of an aluminum alloy containing 2.00-3.00% by mass of Si, 0.05-0.40% by mass of Fe and 0.80-1.80% by mass of Mn, and having a Cu content of 0.20% by mass or less (including 0.00% by mass) and a Zn content of 6.00% by mass or less (including 0.00% by mass), with the balance being made up of Al and inevitable impurities. This aluminum alloy sheet is also characterized in that after a heating test in which the aluminum alloy sheet is heated from 300 C to 400 C at an average heating rate of 60 C/minute or less and is held at 600 3 C for 5 3 minutes, in a cross-section that is perpendicular to the rolling surface and is perpendicular to the rolling direction, the proportion in the width direction of regions having one or more crystal grain boundaries in the sheet thickness direction is not less than 25% but less than 90%, and the average crystal grain size in a direction perpendicular to the rolling direction in the sheet surface is 950 m or less."
The patent application was internationally filed on Mar. 22, 2024, under International application No.PCT/JP2024/011305.
