近日，中铝集团重点投资建设的东北轻合金有限责任公司（以下简称“东轻”）特种铝合金锻造生产线改扩建项目全面投产，这一里程碑事件不仅标志着中铝集团在高端新材料领域的布局实现关键突破，更意味着我国高性能铝合金锻造能力迈入国际先进行列，为国家战略物资保障增添坚实支撑。

战略锚定：践行国家产业升级使命

作为“十四五”期间中铝集团高端新材料板块的核心布局项目，东轻特种铝合金锻造生产线改扩建项目自规划之初便承载着落实中央关于构建现代化产业体系的重要使命。总投资约4.5亿元的该项目，是东轻作为“中国铝镁合金加工业摇篮”，连续三年荣膺国家制造业单项冠军企业后，在高端产能升级上的又一重大举措。

东轻作为中铝集团东北铝加工基地，长期服务于国防军工、航空航天等国民经济关键领域，此次项目建设正是其“高端制造、铝基强国”发展理念的生动实践。项目紧密围绕航空航天、能源交通等领域的“卡脖子”材料需求，通过产能升级与技术革新，进一步强化国家重点材料自主保障能力。

硬核实力：汇聚行业顶尖装备与技术

该项目的核心竞争力源于其汇聚的一系列行业顶尖装备与自主创新技术。生产线配备了国内轻金属行业最大的等温模锻液压机、能力最强的环件胀形机，以及行业首创的底升式加热炉，形成了从坯料加热到精密锻造的全流程高端生产能力。

其中，核心设备等温模锻液压机所采用的等温锻造工艺，通过将金属毛坯与模具共同加热至恒定温度，以低应变速率实现复杂精密锻件的近净成形，可使高温合金变形抗力降低至普通模锻的1/5-1/10，锻件余量减少30-50%，表面粗糙度达到Ra3.2μm以下。这种先进工艺与东轻掌握的三级时效等国际先进技术相结合，将有效提升航空航天用铝合金锻件的组织均匀性与尺寸精度，为高端装备制造提供更高品质的基础材料。

价值凸显：筑牢产业链安全赋能新质生产力

项目投产后，将与东轻现有的国家级研发平台形成高效协同，进一步释放高端产能。依托企业技术中心、博士后科研工作站等科创载体，以及在2X24、7X50等系列合金上积累的国际水平技术成果，生产线将重点保障航空发动机部件、机身结构件、轨道交通关键构件等高端产品的稳定供应。

在民用航空领域，该项目将为东轻推进2X24、7X75合金薄板的产业化提供支撑，助力实现100%民机铝合金国产化目标；在国防军工领域，将进一步满足战术直升机、战斗机等装备对轻量化、高可靠性铝合金材料的需求。从更广阔的产业视角看，项目投产将推动我国铝加工产业向高精尖和高附加值方向升级，对打造自主可控的制造业产业链供应链、培育壮大新质生产力具有深远意义。

作为铝加工产业的“排头兵”，东轻此次项目投产不仅是企业自身转型升级的关键一步，更是我国高端新材料产业突破发展的生动缩影。未来，依托智能工厂建设与数字化转型成果，东轻将持续以技术创新驱动产业升级，为“祖国的银色支柱”续写新的辉煌。
