Formability of Roll Cast Recycled Aluminum Alloy

Article Preview

Fe was added to 6016 aluminum alloy as the impurity, and this alloy was used as the model of the recycled 6016 aluminum alloy. The content of the Fe was from 0.18 mass% up to 1.0 mass%. 6016 including impurity-Fe was cast into the strip using a high speed twin roll caster at speed of 60 m/min. The increase of the content of impurity-Fe makes castability better rather than worse. The formability was investigated by tension test and 180 degrees bending test. The increase of Fe did not have influence on the bending test. There was no crack at outer surface of T4-heat treated strip after 180 degrees bending. The formability of 6016 strip including impurity-Fe cast by the high speed twin roll caster was enough for hem forming. The ductility of Fe added 6016 was improved by the high speed twin roll caster. It is thought that Al-Si-Fe impurity became fine by the effect of the rapid solidification, and deterioration could be improved.
