5A05 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 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 high-strength structural parts. Storage tanks, pressure vessels, and marine components.
