An alloy is a mixture of two or more metals, or a metal and another element, designed to enhance certain properties. Common examples include steel, which is made from iron and carbon, and bronze, a combination of copper and tin. Alloys are often stronger, more resistant to corrosion, or have improved electrical conductivity compared to their individual components. Alloys are widely used in various industries, including construction, automotive, and electronics. They can be tailored for specific applications, such as aluminum alloys for lightweight structures or nickel alloys for high-temperature environments. This versatility makes alloys essential in modern technology and manufacturing.
