Aluminum is a chemical element and a lightweight, soft, silvery-white, nonmagnetic metal in the boron group. It is highly malleable, ductile, and has a strong resistance to corrosion. Aluminum strips, on the other hand, are a specific form of aluminum that has been processed into thin, flat, elongated pieces. These strips are used in various applications such as packaging, construction, and manufacturing due to their strength, flexibility, and conductivity. The main difference lies in their physical form and usage; aluminum is the raw material, while aluminum strips are a processed product.
