资料显示，今年上半年，上海三月期铝最低下探至12635元/吨，倒退回了25年前的价格水平。尽管后期上海三月期铝半年均价反弹到13442元每吨，但仍然同比下跌了近10%。
产能过剩是直接原因。根据中国有色协会统计数据显示，今年上半年中国电解铝累计产量达1150.2万吨，同比增长8.9%。
与此同时，统计数据表明，新疆电解铝的运行产能今年年底将增加到500万吨，从2011年的50万吨左右，最近4年增长了10倍。多位业内人士直言，产能疯长的背后正是地方政府的巨大保增长压力，从而导致铝行业投资热度始终不减，造成了资金、资源和环境的浪费与破坏。
高电费是另一层原因。
中铝半年公告中指出，电费目前已占到电解铝总成本的45%左右。根据数据统计，具有自备电的铝企比电网购买工业电的铝企每千瓦时用电价格低出2角钱以上，从而电解铝的生产成本降低2800元/吨。（中国进出口网）
On August 28, Chinese aluminum industry released half-year performance report, its first-half operating income reached ¥70.1 billion, and the parent company it attributed is ¥4.123 billion loss. Aluminum insiders said the loss was mainly derived from aluminum price’ drop.
Data shows that in the first half of this year, Shanghai March aluminum lowest price dropped to ¥12,635/ton, back to the price 25 years ago. Despite later Shanghai March aluminum’s average price in half an year rebounded to ¥13,442/ton, but still fell by nearly 10%.
Overcapacity is the direct cause. China Nonferrous metals Association data shows that in the first half of this year, China's electrolytic aluminum cumulative production reached 11.502 million tons, increasing by 8.9%.
At the same time, data shows that Xinjiang electrolytic aluminum production can be increased to 5 million tons by the end of this year,. From about 500,000 tons in 2011, aluminum production increased by 10 times in the last four years. Many insiders said, the reason was local goverments’ tremendous pressure to maintain growth, leading to heat the aluminum industry investment, resulting in waste and destruction of capital, resources and the environment.
High electricity grid is another reason.
Aluminum six-month notice said that the electricity has accounted for about 45% of the total cost of electrolytic aluminum. According to statistics, the electricity price (KW/h) of the aluminum industry having owned electricity is lower 2 cents than that of the aluminum industry purchasing industrial electricity, therefore the cost of electrolytic aluminum production reduced to ¥2800/ton.
