Problems solved by technology

However, it is difficult for the copper alloy materials involved in the prior art to take into account multiple properties such as high thermal conductivity, high strength and corrosion resistance at the same time, and the current production process of copper alloys is still the traditional smelting-casting-annealing-forging. Low efficiency, low yield, high energy consumption, it is difficult to achieve continuous production, or, although the production efficiency and yield can be improved, the alloy composition and feeding sequence are relatively complicated

Description

technical field [0001] The invention relates to the technical field of alloy materials, in particular to a high-strength corrosion-resistant copper alloy composite material and its preparation method and application. Background technique [0002] As an efficient and compact heat exchange equipment, plate heat exchanger is widely used in metallurgy, medicine, chemical industry and other fields. The fluid passes through the turbulent flow of the narrow gap between the plates of the plate heat exchanger to exchange heat and cold to achieve the heat exchange effect. The heat exchanger sheet is an important structural part of the plate heat exchanger, which needs to have good corrosion resistance and excellent mechanical properties while having high thermal conductivity. [0003] At present, the main raw materials used to manufacture plate heat exchangers are titanium alloy or stainless steel. However, the cost of titanium alloy is relatively high, the relationship between suppl...
