An alloy is a mixture of two or more elements, where at least one is a metal. Alloys are created to enhance certain properties, such as strength, corrosion resistance, or ductility. Common examples include steel, which is an alloy of iron and carbon, and bronze, made from copper and tin. Alloys play a crucial role in various industries, including construction, automotive, and aerospace. They are essential for creating materials that can withstand extreme conditions and provide durability. The development of new alloys continues to advance technology and improve the performance of everyday products.
