董明珠对空调行业"铝代铜"的公开回应引发广泛关注，她强调格力坚持使用铜管的核心原因是铝材在长 期可靠性和技术保障上仍无法与铜媲美。 一、格力立场与技术争议 明确拒绝铝代铜 董明珠表示，铝在导热性（铜的导热系数约为铝的1.6倍）、耐腐蚀性（尤其酸性环境）及长期冷热循 环下的稳定性（铝膨胀系数高易导致焊口开裂）存在天然缺陷。尽管格力已研究铝代铜技术多年，但铝 材仍无法达到铜管同等质量保障，因此"不敢保证替代后的产品寿命"。 格力官方回应称，目前没有铝代铜计划，铜材在长期可靠性方面的优势是技术替代的前提。 铝材的技术瓶颈 成本与资源压力驱动 物理性能差距：铝的导热效率仅为铜的60%，需增大换热面积补偿；耐腐蚀性弱，潮湿环境易氧化；膨 胀系数高，长期冷热循环可能引发制冷剂泄漏。 验证不足：实验室数据与实际工况存在差异，铝管空调在极端环境（如高湿度、高盐雾）的长期可靠性 缺乏大规模市场验证。 二、行业联盟的推进动因 铜价高企：2025年铜价突破1万美元/吨，单台空调铜材成本占比达20%-30%，而铝价仅为铜的1/4，替 换后可降低单台成本约400元，对年销千万台的企业利润影响显著。 资源安全：中国铜资源进口依赖度超80 ...

董明珠说，以铝代铜，一台空调可以节省488元的成本。为了迎合消费者，格力也想这样做——产品价格低，销量会更大。但是，对消费者来说呢？他们购 买这样的产品，质量可能得不到保障，铝管两三年可能会坏。 董明珠指出，消费者买了以铝代铜的空调，买的的时候可能觉得省钱，但后面的成本大。关键不仅仅是钱的问题，产品出问题，会很闹心，比如天气最热的 时候，空调出问题了，你会很难受。 以前，空调是用铜管的，但这几年，铜的价格飙升，一些空调企业开始用铝取代铜，这样可以大幅降低成本。而很多消费者购买空调，最关注的就是价格， 至于用的是铝还是铜，他们不懂，也不关心。 最近，美的、小米、海尔等空调企业宣布推动"以铝代铜"技术的应用，降低对铜的依赖，这几家企业已经加入空调"以铝代铜"公约。那么，作为空调行业的 龙头企业，格力电器为什么没有加入进来？董明珠怎么看待"以铝代铜"的？ 对于这个话题，董明珠曾谈论过多次。最近，她表示，格力电器也在研究，铝可以代替铜，但替代不了铜的质量。 董明珠透露，格力电器也在研究以铝代铜，已经研究很多年了，在这方面的技术没有成熟之前，没有100%把握之前，格力空调绝对不会以铝代铜。目前的 实验室数据显示，铝代铜 ...
