Aluminium hits two-year high as China capacity limits help rally

Aluminum extended gains to a two-year high after China, the biggest producer, tightened capacity controls across an array of metals to meet emission-cutting goals. The light metal used in everything from window frames to solar panels has climbed with other base metals this year as expected US monetary easing and China’s bid to step up rescue efforts for its beleaguered property sector bolstered demand. Prices are up almost 20% this quarter alone.
