Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and more specifically relates to a preparation method of an aluminum alloy used for manufacturing oil pipes. Background technique [0002] Aluminum is currently the most used non-ferrous metal material in the industry. Aluminum alloys are widely used in various fields because of their light weight and superior performance in all aspects. As the delivery channel in the oil circuit, the oil pipe not only requires good mechanical properties, but also needs to have a certain anti-rust ability to ensure the quality of the delivered oil, and has certain requirements for its service life. At present, aluminum alloys are often used in the production of oil pipes, but the antirust ability of aluminum alloys has always been the key to the manufacture of oil pipes. Contents of the invention [0003] Aiming at the problems of fouling oil delivery and short service life caused by the poor ...
