Aluminum strips and steel sheets differ in material composition, properties, and applications. Aluminum strips are made from aluminum, a lightweight metal known for its corrosion resistance and high thermal conductivity. They are often used in applications requiring light weight and flexibility, such as in electrical wiring or heat exchangers. Steel sheets, on the other hand, are made from steel, which is an alloy of iron and carbon. Steel is stronger and more durable than aluminum, making it suitable for construction, automotive, and heavy machinery. Steel also has higher magnetic permeability and is more resistant to wear. The choice between aluminum strips and steel sheets depends on the specific requirements of the project, such as strength, weight, and environmental conditions.
