Embodiment Construction

[0007] Specific embodiments of the present invention will be further described in detail below.

[0008] The aluminum alloy composition of the present invention is composed of the following weight percentages: 0.20-0.25% of silicon, 0.5-0.8% of iron, 0.05-0.12% of copper, 3.0-3.5% of magnesium, 0.05-0.15% of zinc, 0.15-0.45% of chromium, manganese 0.05-0.1%, the sum of other contents ≤ 1%, and the balance is aluminum.

[0009] In practical applications, this aluminum-magnesium alloy has good corrosion resistance, excellent weldability, good cold workability, and medium strength. The main alloying element of aluminum-magnesium alloy is magnesium, which has good formability, corrosion resistance, weldability, and medium strength. It is used to manufacture aircraft fuel tanks, oil pipes, and sheet metal parts for transportation vehicles and ships, instruments, street lamp brackets and Rivets, hardware products, electrical shells, etc. This alloy has high strength, especially fat...
