What is an alloy? Give two examples of alloys.
A uniform combination of two or more metals or a metal with a non-metal is called an alloy. Alloys are produced by mixing metals in their molten state in desired quantities and allowing the solution to cool at the room temperature. Similarly, an alloy of a metal and non-metal is prepared by dissolving the non-metal in the molten metal and allowing the solution to cool at the room temperature.
Examples: Steel is an alloy of iron. The composition of steel is iron with 0.1 to 1.5 % carbon.
Brass is an alloy of copper and zinc. Its composition is 80 percent copper and 20 percent zinc.
