Difference Between Steel and Copper | Difference Between

Copper is resistant to corrosion in underground environments, and steel can rust. Copper will corrode in moist air, slowly, and darkens forming a layer of copper oxide. Steel, with more carbon and iron in it, will also rust in moist air. Copper is a high conductor, and very popular for thermal and electrical conductivity.
