What are the differences between different grades of hot rolled aluminum coils?

Different grades of hot rolled aluminum coils are distinguished by their chemical composition, mechanical properties, and applications. Grades like 1000 series are pure aluminum with high ductility and electrical conductivity, suitable for general purposes. 3000 series, with added manganese, offer moderate strength and are used in cooking utensils and chemical equipment. 5000 series, containing magnesium, are strong and corrosion-resistant, used in marine applications and aerospace. 6000 series, with silicon and magnesium, are known for their mechanical strength and are used in construction and automotive parts. Each grade has specific alloying elements that tailor its properties for different industrial needs.
