Iron is the most widely used metal, in part because of its natural abundance and low price. Its applications are as varied as are its different commonly used alloys. Pure iron rusts easily and cannot be used for applications in direct contact with air without a protective coating. However, many different alloys such as different grades of steel, impart hardness, flexibility, corrosion resistance and other properties to iron, rendering it one of the most versatile metals in engineering.
