Problems solved by technology

However, the ductility of traditional aluminum alloys is poor. During the extrusion molding process, excellent ductility cannot be achieved, resulting in a thicker aluminum tube wall, which not only consumes a large amount of aluminum materials, but also has an unsatisfactory heat dissipation rate.

Abstract

The invention discloses an aluminum alloy material for forming an aluminum pipe, which is characterized by consisting of the following components in percentage by mass: 1.0-1.3% of manganese, 0.35-0.37% of iron, 0.06-0.08% of silicon, 0.07-0.08% of titanium, not greater than 0.005% of trace impurity elements and the balance of aluminum. The aluminum alloy material for forming the aluminum pipe has the advantages of good ductility and excellent corrosion resistance.

Description

technical field [0001] The invention belongs to the field of material technology, specifically the field of metal alloy materials, in particular to an aluminum alloy material for forming aluminum tubes. Background technique [0002] Aluminum alloy materials are the most widely used non-ferrous metal structural materials in industry, and have been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries. With the rapid development of science and technology and industrial economy in recent years, the performance requirements of aluminum alloys are also getting higher and higher. A large number of aluminum tubes are used in the construction of existing automobile radiators and engineering plumbing equipment. These aluminum tubes require thin wall thickness to meet the requirements of rapid heat exchange. However, the ductility of traditional aluminum alloys is poor. During the extrusion molding process, excellent ductility c...
