<p><P>PROBLEM TO BE SOLVED: To provide an aluminum material capable of achieving a high hem bendability and a high sheet moldability. <P>SOLUTION: The aluminum material is composed of crystal grains of different crystal orientations comprising Brass-oriented grains, Copper-oriented grains and the balance being other crystal-oriented grains. The occupancy ratio of the Brass-oriented grains is 0.2-0.4, the occupancy ratio of the Copper-oriented crystal grains is 0.05-0.1, the total occupancy ratio of these crystal orientations is 0.25-0.5, and the balance is other crystal-oriented grains. An automobile member is obtained using the same. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
