The Quiz: Which of these substances is an alloy?
Tin
Aluminum
Bronze
Zinc
Tin, aluminum, and zinc are all elements on the periodic table, but to be considered an alloy, a material has to be made of two or more elements. Bronze fits that description, as it is a metallic substance traditionally composed of copper and tin. Other alloys include brass, stainless steel, and iron.
The correct answer to this quiz is Bronze.
