What is the chemical composition of aluminum coils?

Aluminum coils are primarily composed of the element aluminum (Al), which is a lightweight, silvery-white, and ductile metal. Pure aluminum is relatively soft, so it is often alloyed with other elements to improve its strength and durability. Common alloying elements include copper, magnesium, manganese, silicon, and zinc. These elements can enhance properties like strength, formability, and resistance to corrosion. The specific composition of an aluminum coil can vary depending on the alloy type and the intended application, but the primary component will always be aluminum.
