May 26 (Bloomberg) -- World unwrought aluminum inventories were 1.21 million metric tons in April, down 14 percent from a year earlier, the International Aluminium Institute said.
Including unprocessed scrap and finished mill products, stockpiles of the lightweight metal declined 12 percent to 2.3 million tons, the London-based institute representing 80 percent of global output said today on its website.
So-called unwrought aluminum refers to metal produced at smelters or from scrap. Stockpiles in warehouses monitored by the London Metal Exchange, the world's largest marketplace for the metal, soared almost 31 percent to 4.5 million tons from the end of March 2009 to April 30.
