Abstract

The invention discloses a high-strength corrosion-resistant AL-Mg alloy. The high-strength corrosion-resistant AL-Mg alloy comprises the following chemical components in percentage by weight: less than or equal to 0.3% of Fe, less than or equal to 0.25% of Si, less than or equal to 0.1% of Cu, 0.4-1.2% of Mn, 4.5-6.0% of Mg, 0.25-0.55% of Zn, 0.10-0.3% of Cr, less than or equal to 0.15% of Zr, less than or equal to 0.15% of Ti, and the balance of Al. The high-strength corrosion-resistant AL-Mg alloy solves the problems that the strength and the corrosion resistance of the conventional aluminum alloy 5083 in the manufacturing of a traffic tool are not good, the tensile strength of the obtained alloy sigma b is more than or equal to 320Mpa, the yield strength sigma 0.2 is more than or equal to 160 Mpa, the ductility delta is more than or equal to 23%, and the grade of an exfoliation corrosion test reaches PA level.

Description

[0001] technical field [0002] The invention specifically relates to an Al-Mg alloy, especially a high-strength corrosion-resistant Al-Mg alloy. Background technique [0003] In recent years, with the rapid development of my country's transportation industry, lightweight transportation has become an inevitable trend, and replacing steel materials with aluminum alloys is an important and effective way to lightweight transportation. [0004] 5083 aluminum alloy is the most widely used in the manufacture of automobiles, trucks, high-speed rail, freight trains, ships and other vehicles, and has become an important material in the manufacture of vehicles. 5083 aluminum alloy has the characteristics of light weight, medium strength, easy forming, and corrosion resistance, which reduces the weight of the vehicle, improves its carrying capacity, and reduces energy consumption. [0005] However, there are still some problems in the application of the current 5083 aluminum alloy. A...
