Aluminum strips are primarily composed of the element aluminum (Al), which is a lightweight, silvery-white, and malleable metal. Aluminum is a pure element and not a compound, so its composition is straightforward. It is found in Group 13 of the periodic table and has an atomic number of 13. In its pure form, aluminum is soft and lacks sufficient strength for many applications, so it is often alloyed with other elements such as copper, magnesium, manganese, silicon, and zinc to improve its strength and durability. These alloying elements can make up a small percentage of the total composition, but they significantly enhance the properties of the aluminum strips for various industrial uses.
