What are the differences between different grades of aluminum coils?

Aluminum coils are differentiated by grades based on their alloy composition, thickness, and specific applications. Common grades include 1000 series (99% pure aluminum, soft and malleable), 3000 series (aluminum-manganese alloys, good for cooking utensils), 5000 series (aluminum-magnesium alloys, used in marine applications), and 6000 series (aluminum-magnesium-silicate alloys, known for strength and used in construction). Each grade has distinct properties such as strength, formability, and corrosion resistance, which determine their suitability for different industries and applications.
