As of late 2013, the capacity of aluminum foil in China, as the world’s largest producer of aluminum sheets, strips and foils, hit 3.4 million tons/a; the capacity of aluminum cold rolling sheet/strip and aluminum hot rolling strip both reached 12.5 million tons/a. In particular, “1+4” hot continuous rolling played a large part of hot rolling strip production line, making up 43.6% of the total hot rolling capacity.
China also boasts the largest net exporter of aluminum rolling products in the world. In 2013, China’s net export of aluminum sheet/strip and aluminum foil realized 1.214 million tons and 699,000 tons. Due to technical shortcomings, most of China’s imports are high-precision aluminum sheet/strip products.
