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 ...
