The 5A05 aluminum tube is an Al-Mg series rust-proof aluminum alloy, which cannot be strengthened by heat treatment. The magnesium content of this alloy is relatively high, and its strength is relatively low, which is similar to the 03 alloy. The alloy can be cold deformed, but the plasticity is reduced. The plasticity of the annealed state is high, and the plasticity of the semi-cold work-hardened state is acceptable. The alloy has good corrosion resistance and is suitable for spot welding, atomic hydrogen welding, gas welding and argon arc welding. Its machinability is poor in the annealed state, and is still in the semi-cold work-hardened state.
5A05 rust-proof aluminum tube is usually used to manufacture pipes that require high process plasticity, good corrosion resistance, medium load bearing, welded oil tanks and other liquid containers, and other parts; wires are used as welding rods and rivets, and rivets need to be anodized. Similar alloys (such as 5456) are used to make armor plates and structural parts. Storage tanks, pressure vessels, and marine parts, etc.
