科技日报讯（记者刘昊）“铝材加工产品同质化、低价竞争等现象还很严重，部分高端铝材还依赖进口，C919大飞机铝材国产化率低于30%。”在近日举行的国际铝产业高质量发展论坛上，中国铝业集团有限公司副总裁田永表示，推动铝产业高质量发展，依然离不开科技创新。

　　“2018年，全国铝材加工综合产量近4000万吨，比2017年增长4%。但实现利润却比上年下降超过40%。”田永说。

　　事实上，当前我国铝产业已建立起了完善的工业体系，铝消费步入了低速增长阶段。“伴随着铝行业依旧存在的结构性矛盾，供给侧结构性改革仍然任重道远，铝产业到了必须走高质量发展之路的关键时期。”

　　长期从事材料科学研究的中国科学院院士葛昌纯表示，材料新技术是材料工业产品质量升级换代的保障和产业升级的前提，更是铝合金产业发展的基础。

　　他认为，我国铝合金产业发展中存在着“重器件、整机、大工程，轻材料”的现象；当问题出现时，才认识到适度超前布置铝合金研发和应用的重要性。而一些企业、科研院所和学校则缺乏对铝合金基础研究和应用研究长期稳定的支持和耐心。

　　“如果不从根本上树立正确的铝合金产学研密切结合的发展观，仍然‘头痛医头，脚痛医脚’，那么有可能今天补上了短板，明天还会出现更多的瓶颈问题。”葛昌纯说，科技创新具有乘数效应，实施铝产业创新驱动发展，可以全面提升产业的质量和效益，推动铝产业发展方式转变。

　　英国商品研究所（CRU）中国区首席执行官约翰·约翰逊预计，2020年，由于汽车行业开始复苏，铝产业增速会出现回升。未来，从全球铝产业来看，增速将会稳定在3%左右。

　　“作为我国制造业重要支撑行业，铝产业进入动能转换的战略机遇期和关键窗口期。”田永说，“在国内资源匮乏、市场竞争日益激烈和呈饱和局面的态势下，必须要实施开放合作战略；建立铝加工研究平台，加大技术改革创新，推出高精产品；扩大铝应用范围，‘以铝代钢、以铝节木、以铝节铜’，重点在交通运输、建筑结构、电力三个领域扩大铝应用。”
