Classification of Metals
Metals are any of a number of chemical elements, such as iron, that are characterized by their physical and chemical properties, such as ductility, malleability, and conductivity. They have been used by humans for centuries and have played a major role in the development of the modern world. Metals are divided into four main categories based on their properties and uses: ferrous, nonferrous, minor, and exotic metals.
Ferrous metals are metallic elements made primarily from iron. These metals are the most common and are used to create the majority of products and structures in the world. Examples of ferrous metals include cast iron and mild steel. These metals are strong and sturdy, making them ideal for construction and infrastructure projects.
Nonferrous metals are metallic elements that do not contain iron. They are lighter and more malleable than ferrous metals, but are nevertheless used in a number of everyday items. Examples of nonferrous metals include aluminum, copper, and brass. These metals are often used in the production of aircraft, ships, and automobiles. They are also used to create electrical wiring and industrial machinery.
Minor metals are the less common types of metals. These include nickel, cobalt, and a number of rare earth elements. They are often used to create specialty alloys and are an important part of the production of high-quality stainless steel and other metals.
Exotic metals are those that are not found in nature and must be produced synthetically. These metals have unique and often highly specialized properties, and so are used for a wide range of applications. Titanium is an example of an exotic metal that is used to create lightweight aircraft and spacecraft frames.
Metals are the foundation of modern society and have a wide range of applications. They are divided into four distinct categories based on their properties and uses: ferrous metals, nonferrous metals, minor metals, and exotic metals. By understanding the properties and uses of each classification of metal, it is possible to choose the right metal for a given application.
