摘要
对不同时期生产的２Ａ１２－Ｏ铝合金进行对比，找出了影响近期生产的２Ａ１２－Ｏ铝合金型材伸长率的因素，进行了调整工艺试验，确定了提高型材伸长率的途径。
The present 2A12-O aluminium alloy profiles with the past ones were contrasted. The factors which have influence on present 2A12-O aluminium alloy profiles elongation were found. The tests for adjusting technological precess tests were done. The methods which improve elongaion of 2A12-O aluminium alloy profiels were presented.
