Common alloys used in aluminum production include 1000 series (99% pure aluminum), 2000 series (aluminum-copper), 3000 series (aluminum-manganese), 4000 series (aluminum-silicon), 5000 series (aluminum-magnesium), 6000 series (aluminum-magnesium-silicone), and 7000 series (aluminum-zinc). These alloys are chosen for their specific properties, such as strength, corrosion resistance, and workability, which make them suitable for various applications like aerospace, automotive, construction, and consumer goods.
