Pure iron is fairly soft and can easily be cause and formed when hot. Its color is silvery white. Iron is easily magnetized. When unite with small amounts of carbon, it becomes steel. The crystal structure and magnetism of iron change changes when it is heated. If an iron magnet is heated chromatic hot, it loses its magnetism except regains it when it is cooled.

Modern life depends greatly on iron, the most widely used of all metals. Iron, usually in the form of steel, is nearly ceaselessly helping to do the job.
