The main components of 5000 series aluminum alloys are aluminum and magnesium, which are characterized by medium-high strength, excellent seawater corrosion resistance, excellent welding performance, and the highest strength. The hardness of work hardening aluminum alloys (5xxx>3xxx>1xxx), and the general strength grade is about 300Mpa. The products are mainly used in marine materials, coastal construction materials, optical supplies, structural materials, cryogenic containers, etc.
Commonly used 5000 series alloys are: 5005 5049 5050 5051 5052 5056 5083 5086 5182 5186 5383 5456 5754
