有色金属材料的发展趋势 1.有色金属材料生产向高精度、高性能、低消耗、低成本方向发展 随着科学技术的发展,现代工业、现代国防和人民生活用产品都向高精度、高性能、低能耗、低成本方向发展。因此,要求与之相关的有色金属材料也同步向高精度、高性能、低能耗、低成本方向发展。如廉价的钕铁硼永磁材料,其矫顽力、居里温度等性能明显提高,社会效益和经济效益十分显著;又如,在发达国家,水箱铜带材与汽车工业的技术进步同步发展,汽车水箱普遍使用管带式水箱,水箱铜带的厚度已减薄到0.038～0.045mm,最薄达到0.025mm。使水箱的散热性能更好,结构也更加紧凑,
Non-ferrous materials development trend 1. Production of non-ferrous metal materials to high-precision, high performance, low consumption, low cost direction With the development of science and technology, modern industry, modern defense and people’s life products are high-precision, high performance , Low energy consumption, low cost direction. Therefore, the related non-ferrous materials are required to be simultaneously developed to high precision, high performance, low energy consumption and low cost. Such as cheap NdFeB permanent magnet materials, its coercivity, Curie temperature and other properties significantly improved, social and economic benefits are significant; another example, in developed countries, water tank copper strip and the simultaneous development of technological advances in the automotive industry , The common use of car water tank water tank, water tank copper thickness has been reduced to 0.038 ~ 0.045mm, the thinnest reached 0.025mm. So that better thermal performance of the tank, the structure is more compact,
