Aluminum alloy sheet with good forming workability and method for manufacturing same |
| 摘要 |
Disclosed herein are: (1) a formable bake-hardening type aluminum alloy sheet, containing 0.2-0.7 wt % of Fe, 0.05-0.5 wt % of Cu, 0.5-2.5 wt % of Mg, 0.5-2.0 wt % of Mn and optionally 0.05-1 wt % of Zn under the condition of Fe wt % +(Mn wt %x1.07)+(Mg wt %x0.27)</=3.0, and intermetallic compounds of less than 45 microns in size and an areal rate of 0.5-5% as observed from the surface of a rolled sheet and an average crystal grain width smaller than 25 microns; and (2) a method for producing such bake-hardening type aluminum alloy sheets.
