Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. Instead of the standard YS/T 309-1998 "remelting aluminum rare earth alloy ingot." Compared with this standard YS/T 309-1998, the main changes are as follows. --- Adopted new grades that way; --- New addition AlRE2, AlRE4, AlRE6, AlRE8 four remelting aluminum rare earth alloy grades; --- Added other single impurity content of different grades of product requirements; --- Adjusted grades AlRE0.06 of impurity elements, tightened requirements for the content of Si; --- For the ingot and ingot weights are predetermined; --- Canceled a color flag, flag label content increases. This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized. This standard is drafted by. Baotou Aluminum Co., Ltd. The main drafters of this standard. Zhao Hongsheng, Wang Yunli, Dong Jianxiong, Chen Qinghua, Jian-Hua Jin, Li win glory, Zhang Chunming, Chai Maolin. Remelting aluminum rare earth alloy ingot
