Abstract

The invention relates to aluminum alloy materials, in particular to a corrosion-resistant aluminum alloy material. The corrosion-resistant aluminum alloy material comprises, by mass percentage, 0.01-0.05% of Cu, 0.2-0.8% of Mg, 0.10-0.31% of Mn, 0.2-0.9% of Si, 0.1-0.5% of Fe, 0.01-0.09% of Zn, 0.1-0.65% of Cr, 0.001-0.088% of Ti, 0.02-0.35% of Li, 0.3-1% of Sn and the balance Al and trace impurities. The corrosion-resistant aluminum alloy material has the beneficial effects of being quite high in strength, excellent in forming performance, good in welding performance and good in corrosion resistance. The surface of the product immersed for a long time after being worn is in good condition, almost no scratches and other damage exist, as the immersion time goes on, no obvious corrosion product is accumulated on the sample surface, and thus the corrosion-resistant aluminum alloy material has the good corrosion resistance.

Description

technical field [0001] The invention relates to the field of aluminum alloy materials, in particular to corrosion-resistant aluminum alloy materials. Background technique [0002] The special environment of the ocean has certain special requirements for metal materials, such as corrosion resistance, water tightness, light weight, etc., while aluminum alloy has the characteristics of low density, high light weight, good electrical and thermal conductivity, corrosion resistance and easy processing It meets this requirement very well, so it is well applied in the marine environment. During the manufacturing process of aluminum alloy or under atmospheric corrosion, a highly adherent hydrated alumina film will be formed on the surface to make it corrosion resistant, but the frictional damage of aluminum alloy in the marine environment will destroy the surface film and affect its corrosion resistance. Contents of the invention [0003] The object of the present invention ...
