据日本主要汽车生产厂家预测,随着汽车轻型化的飞速发展,到2000年汽车的主要材料也将由钢铁转为铝材。最近,日本在主要汽车生产厂家进行的汽车轻型化摸拟中,预计汽车的平均质量将由1989年的1300kg降至2000年的850kg,质量减轻35%。在材料方面,原来钢铁占汽车总质量的69%将降至24%,而铝材由原来的4%升至32%。由此,日本的主要钢铁生产厂家意识到了危机,开始与铝厂携手合作、共同开发汽车用料。如:新日本制铁公司与SKY铝公司合作,川崎制铁公司与古河铝厂合作等。由于石油资源有耗尽的危险及核发电的自然条
According to the forecast by major Japanese car manufacturers, with the rapid development of automobile light-weight, the main material of automobiles will also be converted from steel to aluminum by the year 2000. Recently, in Japan’s light-weight car simulation conducted by major automobile manufacturers, the average car quality is expected to drop from 1300kg in 1989 to 850kg in 2000, a 35% reduction in quality. In terms of materials, 69% of the total mass of steel and steel will be reduced to 24%, while the aluminum rose from 4% to 32%. As a result, Japan’s major steelmakers realized the crisis and began to work with aluminum mills to jointly develop automotive materials. Such as: Nippon Steel Corporation and SKY Aluminum Corporation, Kawasaki Iron and Steel Company and the ancient river aluminum plant cooperation. Due to the depletion of oil resources and natural nuclear power generation
