Final answer:
Malleability is the property of a material that allows it to be bent into shape without breaking. This property is helpful in construction materials because they do not shatter under pressure or hammering. Metals, such as copper, are malleable and ductile.
Step-by-step explanation:
Malleability is the property of a material that allows it to be bent into shape without breaking. This property is especially helpful in construction materials because they do not shatter under pressure or hammering. Metals, such as copper, are malleable and ductile, meaning they can be stretched into thin wires. For example, when making electrical wires, the malleability of copper allows it to be easily shaped into the desired form.
