    摘要: A Cu/Al composite pipe and a manufacturing method thereof are disclosed. The inner layer of the pipe is Cu, and the outer layer is Al. The combinative layer is formed between the two layers due to mutual diffusion of Cu and Al. The raw composite pipe is rolled with single rolling by a planetary rolling machine, wherein the rolling process has the single pass percentage reduction of area of 50%˜95%, an exit rolling speed of 5˜30 m/min, a temperature in the deformation area of 200° C. ˜600° C. The pipe can be used in many fields, such as architecture, refrigeration, air-conditioners, refrigerators, solar energy, water heaters, condensers and radiators, etc.
