Alloys are materials made by combining two or more metals, or a metal with another element. This mixture enhances certain properties, such as strength, durability, and resistance to corrosion. For example, steel is an alloy of iron and carbon, which makes it much stronger than pure iron alone. Alloys are widely used in everyday items, from jewelry to automobiles. By adjusting the composition of an alloy, manufacturers can create materials tailored for specific purposes. For instance, bronze, an alloy of copper and tin, is known for its resistance to wear and is often used in sculptures and coins.
