ALUMINUM ALLOY SHEET FOR PRESS FORMING, PROCESS FOR MANUFACTURING SAME, AND PRESS-FORMED PRODUCT THEREOF |
摘要 |
The present invention provides an aluminum alloy sheet for press forming, said aluminum alloy sheet being made of an aluminum alloy that contains 0.4 to 1.5 mass% of Si and 0.3 to 1.0 mass% of Mg with the balance being Al and unavoidable impurities and exhibiting a ratio (P(%)) of &Dgr;L to L0 of 2.0% or less [wherein: L0 is the length of a diagonal line lying at an angle of 0º to the rolling direction in an indentation formed by a Vickers hardness tester; and &Dgr;L is a difference between L0 and the length (L45) of a diagonal line lying at an angle of 45º to the rolling direction therein]. Further, the present invention provides a process for manufacturing the aluminum alloy sheet and a press-formed product thereof. |
