Description

Technical field [0001] The invention relates to the technical field of metal materials and metal material processing and molding, in particular to a high-strength corrosion-resistant collecting pipe material and a manufacturing method thereof. Background technique [0002] Aluminum and aluminum alloy strip materials are one of the important raw materials for national economic and social development. Automobiles have become a hot product for mass consumption. In 2016, my country sold 28 million vehicles. As the main material of automobile heat exchange devices, aluminum is required to work under high-strength conditions to achieve both thin-walled and high-strength And high corrosion resistance. At present, the new trend of heat exchanger development is to use materials to reduce the weight and cost of heat exchangers. With the continuous innovation of technology, continuous improvement of quality and increasingly fierce market competition, this requires the strength of the materi...
