The corrosion resistance of both alloys decrease after these alloys were recrystallization annealed at temperature of 350 0C for 25min for 5083 this increasing was from 2.493 × 10-3 to 51.24 × 10-3and for 5086 it was from 187.7 × 10-6 to 24.41 × 10-3 both alloys will suffer from localized corrosion as a result of recrystallization annealing. The yield, tensile stress and hardness of both alloys decrease, the tensile stress of 5083 decrease in the percentage of 9.8%, while the yield decrease in the percentage of 15%For 5086 it was 5.071% and 10% respectively while the elongation of both alloys increase in the percentage of 20%. The hardness of 5083 and 5086 increase in the percentage of 17.6% and 23% respectively.
