Problems solved by technology

However, when the existing aluminum alloys are finally processed into thin-walled pipes, because the ductility of aluminum alloys is lower than that of copper, cracks or leakage are prone to occur, and the corrosion resistance of existing aluminum alloy materials is not satisfactory.

Description

technical field [0001] The invention belongs to the field of metal materials, in particular to a method for preparing an alloy material of a fuel delivery pipe for a vehicle. Background technique [0002] At present, the alloy materials of fuel pipelines for vehicles are mainly iron alloys or copper alloys. However, because iron alloy pipes are not flexible, the cost of using copper pipes is also high, and the proportion of copper is large, which increases the overall weight of the vehicle. [0003] The specific gravity of aluminum is low, and there are many advantages in using aluminum alloy to replace copper or iron to manufacture vehicle oil pipes. However, when the existing aluminum alloys are finally processed into thin-walled pipes, because the ductility of the aluminum alloys is lower than that of copper, cracks or leaks are prone to occur, and the corrosion resistance of the existing aluminum alloy materials cannot meet the requirements.
