As the continuation of the previous report, some test of large dimension deep drawing was done to find out the correlation with "earing" and "orange-peel" of aluminium sheet having some different ratios of Fe:Si, as this was concidered to be an important factor to determine orientation of the sheet.The experiment was done with following conditions;1) Material: 2S aluminium sheets with Fe:Si ratio of 1:1, 1.6:1, 2.6:1 respectively.2) Soaking: 4 and 8 hours under 520°C, 8 hours under 500°C.3) Cold rolling: 92% and 90% reduction, in one way only as well as in cross way rolling.4) Annealing temperature: 1 hour under 330°, 350°, 375°and 400°C respectively.As a conclusion, it was found that a working condition with which the aluminium sheet without "orange-peel" and less "earing" can be attainable in some extent.This investigation was done with the fund afforded by Scholarship Committee of the Institute of Light Metal Foundation, for which we are extremly gratefull.
