摘要 AI需求连动铜箔加工费上涨。 3月18日，德福科技在互动平台表示，公司目前处于满产的高负荷运行状态，下游市场需求旺盛、 景气度较高。 公司称，前期已对全球某头部覆铜板厂商供应的HTE、RTF等产品加工费启动提价，近期又已对部 分电池客户供应的锂电铜箔各系列产品加工费启动提价。 放在过去两年锂电铜箔行业深度承压的背景下，这一表态的意义，不只是又一家企业释放经营改善 信号，而是价格端终于出现了更清晰的修复迹象。 过去行业更常见的表述，是开工率回升、订单改善、极薄化产品占比提升、亏损收窄；而像德福科 技这样，直接公开确认已对部分锂电客户启动加工费提价的口径，并不多见。 从公开披露看，德福科技并非孤立个案。 中一科技在2025年年度业绩预告中称，受益于行业景气度回升，铜箔产品平均加工费价格有所上 涨，公司同时积极开发新客户、优化客户结构、提升高附加值产品占比，推动盈利能力显著改善并 实现扭亏。 嘉元科技的公开表述也传递出相似信号。公司在2025年业绩预告中表示，下游市场需求回暖带动铜 箔产品产销量增长，同时高附加值产品占比提升，推动平均加工费上涨，叠加产能利用率提升和降 本增效，最终带动公司实现扭亏为盈。 铜冠 ...
