Malleability is a property of materials, particularly metals, that allows them to be shaped or deformed without breaking. When a malleable material is subjected to pressure, it can be stretched or compressed into thin sheets or various forms. Common examples of malleable metals include gold, copper, and aluminum. This property is essential in various industries, as it enables the production of items like coins, jewelry, and automobile parts. Malleability is often tested by hammering or rolling the material, demonstrating how it can be manipulated while maintaining its integrity.
