Summary: Alloys are materials made by combining two or more metallic elements. They are widely used in various industries due to their desirable properties, such as strength, durability, and resistance to corrosion. Alloys can be classified into different types based on their composition and properties, including ferrous alloys, non-ferrous alloys, and intermetallic compounds. The process of alloying involves melting and mixing the constituent metals, followed by cooling and solidification. Alloying can alter the properties of the base metals, resulting in improved performance and new applications.
