What are the differences between different types of aluminum sheet materials?

Aluminum sheet materials vary based on alloy composition, thickness, and surface treatment. Common types include 1000 series (99% pure aluminum), 3000 series (alloys like 3003 and 3004), 5000 series (magnesium alloys), and 6000 series (magnesium-silicon alloys). Each series has distinct properties: 1000 series is soft and ductile, 3000 series offers moderate strength and good formability, 5000 series has high strength and corrosion resistance, and 6000 series is known for its strength and excellent weldability. Thickness and temper (hardness) also affect performance, with thinner sheets being more flexible and harder tempers offering greater strength. Surface treatments like anodizing or painting can enhance appearance and corrosion resistance.
