Aluminium alloy strip with improved surface visual appearance and method for producing thereof |
摘要 |
An aluminum alloy strip is produced by hot rolling and/or cold rolling of an aluminum alloy chosen from type AA 3xxx, AA 5xxx, AA 6xxx and AA 8xxx. The completely rolled aluminum alloy strip has luminance value (L*) increase of more than 5 after a degreasing process in comparison to the greased roller state in surface color measurement in the CIE L*a*b* color space using a normal light type of D65 and normal observation angle of 10[deg] with the exclusion of the direct reflection in a 45[deg] /0[deg] geometry. An independent claim is included for preparation of aluminum alloy strip. |
