Which is an example of an alloy?

An alloy is a mixture of two or more elements, where at least one of the components is a metal. Bronze is a classic example of an alloy, as it is primarily made from copper and tin. The properties of bronze, such as its strength and resistance to corrosion, are significantly enhanced compared to its individual components when mixed.

On the other hand, iron and aluminum are both pure metals in their base forms. Gold, while often used in its pure form, can also be alloyed with other metals to create various karats, but in the context of the question, it is considered a pure metal as well. Thus, bronze stands out as a true example of an alloy, demonstrating the unique characteristics that arise from combining metals.
