4. aluminum

Answer 1

4. Aluminum is a material that can substitute for copper and reduce copper mine production in certain applications. Aluminum is lighter, cheaper, and more abundant than copper, and it can conduct electricity almost as well as copper. Therefore, aluminum is commonly used in electrical transmission lines, heat exchangers, and other applications where copper was traditionally used.
