The main 5xxx series alloy used is AA5083 alloy. Others include AA5086, AA5454 and AA5754 alloys, which are all non-heat treatable alloys.
gold. The mechanical properties of the alloy depend on the chemical composition of the alloy and the hot rolling temperature. The supply status of marine AA5083 alloy is O status (hot rolled, rolled
fire), H111 and H116 conditions (hot rolling, work hardening, stabilization treatment). The latter is a stress corrosion resistant state, which can prevent tropical weather
This can lead to intergranular corrosion and fracture of the material.
