There are two elements that are very strong and useful. Many people use aluminum each day. They use aluminum foil to wrap things with. They may drink out of a soda can that is made of aluminum. People also use things that are made out of steel. Some refrigerators are made out of steel. Even though both metals are very strong and useful, they are different.
Aluminum is lighter than steel, and steel has some qualities that are magnetic whereas aluminum is not magnetic. If you need something to weld, steel would be your best answer because it is better than aluminum. Steel is stronger when it comes to lasting longer. Aluminum will not last very long compared to steel.
