Technical Report of Aluminum Alloy Brazing Materials

Aluminum alloy brazing material is mainly used for oxygen equipment and automotive radiator, it is because of light weight, corrosion resistance, good brazing, reliable performance and other advantages are widely used, with the rapid development of China's auto industry and air separation plant Process improvement, the brazing material coating thickness uniformity, size, performance and other indicators have been updated higher requirements. At present, the domestic production of automotive radiators and air conditioners with a large number of large-scale aluminum alloy brazing materials rely heavily on imports. Therefore, in order to meet the needs of China's auto industry development goals, to achieve China's automobile industry, lightweight and localization, and promote the development of other related industries, saving foreign exchange, saving energy and enhance China's automotive products in the international market competitiveness, The development of large-scale aluminum alloy brazing foils and air separation equipment brazing plates for automobiles has a very important strategic significance.
