智通财经APP获悉，东吴证券发布研报称，轻量化设计正成为人形机器人迭代的核心方向，通过优化结 构、选用轻质材料（如镁合金、碳纤维、PEEK等）可显著提升续航与动态响应速度。当前头部厂商通 过自研高扭矩密度电机、拓扑优化结构等手段持续减重，未来镁合金与PEEK材料在多材料协同应用中 潜力突出。 东吴证券主要观点如下： 镁合金密度仅为铝合金的2/3，却在比强度、减震性、电磁屏蔽性和加工性能等方面展现出综合优势。 尤其适用于对轻量化、吸能性和成型效率要求较高的结构件。过去镁合金高成本、成型工艺复杂性与耐 蚀性三大问题制约其工业化落地，价格与工艺的同步改善助推镁合金渗透率提高。价格方面：2021年前 镁铝价格比长期高于1.5，镁材渗透动力不足;近年来伴随镁材价格走弱，镁铝比降至接近1.0，价格压力 逐步缓解。工艺方面：半固态镁合金压铸工艺提高镁合金加工工艺安全性，复合涂层工艺提高镁合金抗 腐蚀与抗氧化能力，镁合金使用性能不断提高。近年来压铸机龙头企业纷纷布局半固态镁合金压铸设 备，星源卓镁采购了伊之密的镁合金压铸设备用于生产新能源汽车零部件，博奥镁铝采购海天金属的镁 合金压铸设备用于加工仪表盘横梁支架。埃斯顿与宝武镁 ...
