Common types of aluminum alloys include 1000 series, which are nearly pure aluminum; 2000 series, known for their strength due to copper content; 3000 series, which are alloyed with manganese for good formability; 5000 series, featuring magnesium for improved strength and corrosion resistance; 6000 series, which are popular for their strength and heat treatability; and 7000 series, recognized for their highest strength among aluminum alloys, often used in aerospace and automotive applications. Each series offers unique properties that make them suitable for specific applications.
