The structure and industrial environment of aluminum-built ships require materials to have good corrosion resistance, weldability, plasticity and certain resistance, yield strength, ductility, impact resistance and other properties.
The aluminum alloys that meet these properties and can be used the most and have the best effects on ships include industrial 1xxx pure aluminum, 5xxx series and 6xxx series alloys. In recent years, 7xxx series alloys have also attracted increasing interest.
The basic series of marine aluminum alloys are 5xxx series alloys (plates) and 6xxx series alloys (extruded profiles).
