An alloy is a mixture of two or more elements, where at least one element is a metal. Alloys are created to enhance the properties of the base metal, such as strength, durability, or resistance to corrosion.
Two examples of alloys are:
1. Steel: An alloy of iron and carbon, used in construction and machinery due to its strength.
2. Bronze: An alloy of copper and tin, used in making sculptures and coins due to its corrosion resistance.
