Alloys are mixtures of two or more metals or a metal and non-metal that have been combined to create a new material with specific properties. Here are some examples of alloys and their composition: Steel: Steel is an alloy made of iron and carbon. It also has small amounts of other elements such as manganese, silicon, and phosphorus. Steel is strong, durable, and versatile, and it is used in a wide range of applications, including construction, transportation, and manufacturing. Bronze: Bronze is an alloy made primarily of copper and tin, with small amounts of other elements such as zinc and lead. Bronze is strong, corrosion-resistant, and has a low melting point, which makes it easy to cast. Bronze is often used in sculptures, musical instruments, and bearings. Brass: Brass is an alloy made primarily of copper and zinc, with small amounts of other elements such as lead and tin. Brass is strong, corrosion-resistant, and has a low melting point, which makes it easy to cast. Brass is often used in musical instruments, plumbing fixtures, and decorative items. Stainless Steel: Stainless steel is an alloy made primarily of iron, chromium, and nickel, with small amounts of other elements such as carbon and molybdenum. Stainless steel is highly resistant to rust and corrosion, making it a popular material for use in kitchen appliances, medical equipment, and industrial machinery. Aluminum Alloy: Aluminium alloys are mixtures of aluminum and other elements such as copper, magnesium, and silicon. Aluminum alloys are strong, lightweight, and corrosion-resistant, making them popular materials for use in aircraft, cars, and bicycles.
