近年来,我国的铝工业发展很快,1985年原铝的产量已达到53万吨,而铝的消费量达到85万吨。近年来我国铝的消费量及铝材的产量见表1。1985年国内缺少原铝32万吨,主要靠进口铝锭和铝材来解决。我国铝材生产的发展也很快,特别是建筑型材和板带材。铝合金材料除航空、航天等军事工业部门需要以外,已广泛应用到国民经济和人民日常生活的各个领域,如交通 In recent years, China’s aluminum industry has developed rapidly. In 1985, the output of primary aluminum reached 530,000 tons while the consumption of aluminum reached 850,000 tons. In recent years, China’s consumption of aluminum and aluminum production in Table 1. 1985 lack of 320,000 tons of primary aluminum, mainly imported aluminum ingot and aluminum to solve. The development of aluminum production in China is also very fast, especially in building profiles and strip and strip. In addition to aviation and aerospace needs of the military industrial sector, aluminum alloy materials have been widely applied to various fields of national economy and people’s daily life, such as transportation
