5654 aluminum alloy is usually used to manufacture welded pipes, welded fuel tanks and other liquid containers, and other parts that require high process plasticity, good corrosion resistance, and medium load; wire rods and rivets need to be anodized. In foreign countries, similar alloys (such as 5456) are used to make armor plates and high-strength structural parts. Storage tanks, pressure vessels, and marine products parts, etc.
Main features and application scope of 5654 aluminum alloy marine sheet plate
 
It is aluminum-magnesium rust-proof aluminum (5B05 has a slightly higher magnesium content than 5A05). Its strength is equivalent to that of 5A03. It cannot be strengthened by heat treatment; it has high plasticity in annealed state and medium plasticity when it is hardened by semi-cold work. It uses hydrogen atom welding, spot welding, and gas welding. , The welding performance of argon arc welding is still good; the corrosion resistance is high, the machinability is inferior in the annealed state, the machinability is good when the semi-cold work hardened, and the rivets need to be anodized.
Performance characteristics and application of 5654 aluminum alloy


 
5654 aluminum alloy marine plate sheet  is Al-Mg series anti-rust aluminum alloy, which cannot be strengthened by heat treatment. The alloy has higher magnesium content and lower strength, which is similar to 5A03 alloy. Cold deformation of the alloy can increase the strength, but the plasticity is reduced. The plasticity in the annealed state is higher, and the plasticity in the semi-cold hardened state is acceptable. The alloy has good corrosion resistance and acceptable weldability. It is suitable for spot welding, atomic hydrogen welding, gas welding, and argon arc welding. Its machinability is poor in annealed state, and its semi-cold hardened state is still good.
