In a stellar year for base metals, aluminum has led the pack. Now, producers say surging raw material costs could drive prices even higher.
Alumina, the raw material used to make aluminum, has jumped 56 percent since August after China shut down some production, triggering a wave of buying by traders and aluminum smelters. The rally is putting a strain on metal producers in China, where alumina accounts for 40 percent of the cost of making aluminum.
Cost pressures could worsen in the months to come as Chinese environmental reforms weigh most heavily on bauxite and alumina producers. That may give extra fuel for aluminum’s 28 percent rally this year, the biggest since 2009.
