Brass is an alloy of _____ and _____ metals which shows significant ductility.

Alloys

• An alloy is a homogeneous mixture of two or more metals, or a metal and a non-metal.
• Properties of metals can be enhanced by the addition of certain metals or elements.

Brass

• It is an alloy of $66\%$copper and $34\%$ zinc.
• So, brass is an example of a homogeneous mixture.
• Brass is a solution of the molten copper in molten zinc.

So, Brass is an alloy of copper and zinc metals that shows significant ductility.
