Why Is Copper Better Than Aluminum

Satisfactory Essays
To choose the use of copper over aluminum, you need to consider conditions such as electrical conductivity. Copper conducts electricity better than aluminum because of its high capacity over volume. Another factor to consider when choosing one element over the other is expansivity. When materials are used to make contacts expand, their clamping force increases hence deforming points of contact while creeping them. This condition makes aluminum less suitable for making electrical contacts than copper. The reactivity of copper is higher than that of aluminum hence making it less suitable to make cooking pots and pans. Aluminum is best suited because it forms a thin film of aluminum oxide that does not
