Abstract

The invention provides corrosion-resistant aluminum alloy. The corrosion-resistant aluminum alloy comprises, by weight percentage, 14%-35% of silicon, 12%-25% of magnesium, 17%-25% of copper, 25%-30%of titanium, 17%-19% of chromium, 11%-23% of cerium, 16%-32% of strontium and 13%-45% of aluminum. The corrosion-resistant aluminum alloy has the advantages that the number of cold shuts and cracks onthe surface is reduced, the elongation is high, and the elongation and the impact toughness are improved.

Description

technical field [0001] The invention relates to a corrosion-resistant aluminum alloy. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. Aluminum alloy has low density, but relatively high strength, which is close to or exceeds that of high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry, and its usage is second only to steel. . Some aluminum alloys can be heat treated to obtain good mechanical properties, physical properties and corrosion resistance. The existing aluminum alloy has many cracks and poor elongation. Contents of the invention [0003] The problem to be solved by the present invention is to provide a corrosion-resistan...
