Iron is a conductor of electricity. Its electrical resistivity is 9.71 microohm centimeter. In comparison to copper, it is a poorer conductor of electricity. Nevertheless, generally, it is considered a good conductor of electricity.
Iron is one of the most widely used metals because it is strong, easily formed, malleable and cheap. There is reinforcing iron in concrete buildings. Vehicles are primarily made of iron. In the presence of oxygen and water, iron rusts. To prevent rusting, iron is coated with plastic, painted or plated with other metals like zinc and chromium. Galvanizing refers to plating iron with zinc. Certain iron car wheels and water taps are plated with chromium to prevent rust and provide a polished look.
