Alloys are materials made by mixing two or more elements, usually metals. These mixtures create materials with different properties than pure metals. Examples include steel, made from iron and carbon, and bronze, made from copper and tin. Alloys are used to make tools, machines, and structures.

Alloys are found in buildings, vehicles, and equipment around the world. They are used in construction and manufacturing. Different alloys are chosen for different purposes based on their properties.

Alloys have been developed and used by humans for thousands of years. They are part of many technologies and materials in daily life. Alloys are widely used in modern industries.
