For a long time, electrolytic aluminium ,coal,steel and other industries acquire much attention because of the high energy consumption and excess capacity.Steel, coal and other industries to decrease excessive industrial capacity achieved remarkable achievement in 2016. In 2017 the decreasing excessive industrial capacity of the non-ferrous metal industry was on the agenda. Among non-ferrous metals, electrolytic aluminium is the most obvious in the excess capacity industry .

According to estimates,  China has about 439 thousand tons of aluminum production capacity in 2017.To comparing in 2016, 41800 thousand tons of production capacity forecast its growth 10%.If aluminum industry promote the reform of the supply side, the new capacity delivery will be delayed in 2017 . Its pressure of excess capacity will be relieved.
