摘　　要：金属材料是人类社会发展的战略资源,在国内矿产资源日趋减少及国际资源竞争加剧的背景下,寻求金属材料的可持续发展是保障我国资源安全、满足工业需求的必要措施。铝合金作为第二大金属材料,由于耐蚀性好、回收再生能耗污染小,是最具有回收再生价值的金属材料,但在铝合金可持续发展中存在降级回收这一问题。本文从回收与再生角度进行分析,提出精细化分选与强化提纯除杂的方向,考虑到全生命周期循环,对未来的铝合金设计方向及服役过程加以综述,最后对铝合金未来可持续发展进行了展望,期望以铝合金为代表,为金属材料可持续发展的实施策略提供参考。Metal materials are strategic resources for the development of human society.In the context of decreasing domestic mineral resources and the intensification of international resource competition,the sustainable development of metal materials is necessary to ensure the safety of China's resources and meet the needs of industry.As the second largest metal material,aluminum alloy is the most valuable metal material for recycling due to its good corrosion resistance,low pollution and low energy consumption.In the sustainable development of aluminum alloys,there is a problem of recovery from degradation.From the perspective of recovery and regeneration,measures for fine sorting and strengthening purification and impurity removal are proposed.Considering the cycle of the whole life cycle,the future design direction and the service process of aluminum alloys are reviewed.Finally,the future sustainable development of aluminum alloys is proposed,hoping to provide a reference for the implementation of strategies for the sustainable development of aluminum alloy metal materials.
