Abstract: On the basis of analyzing the policy development of recycled cast aluminum alloy, the industry development overview and the implementation effect of the standard, the old and new standards of GB / T 38472 are compared from the perspectives of classification difference and technical difference. Based on the main technical changes of the new version of the standard, the countermeasures and suggestions such as strengthening the publicity and implementation of the new standard, carrying out the standardization pilot demonstration, promoting the reuse process upgrading, and creating a social reuse atmosphere are put forward to help the comprehensive implementation of the new standard.

Keywords: reclaimed cast aluminum alloy; national standard; standard comparison; circular economy

1再生铸造铝合金行业概况

1.1再生铸造铝合金行业相关政策

2020年4月,欧洲铝业协会宣布启动“再生铝行动计划”,力争到2050年再生铝占到铝供应量的50%,替代高碳排放的进口原铝,以达到在降低进口铝依赖度的同时降低碳排放46%的目的。(剩余4290字)
