5456 Aluminum Alloy is a forged aluminum-magnesium alloy developed by adding Mn, Cr, Ti, and Be elements and strictly controlling impurity content. It offers good room-temperature strength and excellent seawater corrosion resistance. The alloy can be formed by rolling, extrusion, and cold working, which increases its strength but reduces its ductility. It is well-suited for the manufacture of high-strength welded structures and pressure vessels.
5456 aluminum is favored for its excellent weldability and machinability, and it is widely used in shipbuilding, storage tanks, and other structural applications, particularly where long-term durability and reliability are required in harsh marine environments.
