Metallic alloys are materials made by combining two or more metals, or a metal with non-metals, to enhance their properties. These mixtures can improve strength, durability, corrosion resistance, and other characteristics compared to pure metals. Common examples include steel, an alloy of iron and carbon, and bronze, which is made from copper and tin. Alloys are widely used in various industries, including construction, automotive, and aerospace, due to their improved performance. The specific combination of metals in an alloy can be tailored to meet particular requirements, making them essential for creating tools, machinery, and structural components.
