5A05 aluminum alloys round bar are commonly used in the manufacture of welded pipes, welded fuel tanks and other liquid containers that require high process plasticity, good corrosion resistance, medium loads, and other parts; wires are used as electrodes and rivets, and rivets need to be anodized. In foreign countries, approximate alloys (such as 5456) are used to make armor plates and high-strength structural parts. Storage tanks, pressure vessels, and marine parts.
