Metals in the Plant

Course Number: 715

The first six chapters of the Metals in the Plant textbook focuses on the two most important commercial metals-iron and steel. Their origins, properties, and uses are described and shown in illustrations. The end of the textbook provides an overview of eight other important metals, their properties and uses, ranging from copper and aluminum to tin and zinc. In its entirety, this textbook provides a thorough overview of the principal metals in commercial use.
