In order to achieve a sustainable development of aluminum industry, aluminum flow analysis for the life cycle of aluminum products in China was necessary. Aluminum flow in the aluminum products life cycle of 2003-2007 in China has been analyzed, from which the following data were resulted. Resources self-support ratio in alumina production, aluminum production and the aluminum industry dropped, increased and leveled off in the period 2003-2007, respectively. Self-produced aluminum scrap use ratio was in the range 5-7%, and the situation of the aluminum scrap lacking state can’t be settled in case of fast increment of aluminum production. Proposals for the sustainable development of aluminum industry in China were put forward.
