Both copper and tin are malleable and easily bent, but bronze, even though it is a combination of the two, is stronger than both. An “alloy” is a metal that is made up of two or more metallic substances that have been combined.

Example:  “Rose gold is an alloy of copper and gold that is found in several places in the Middle East and eastern Europe; the copper gives the metal a lovely reddish hue that makes it a popular choice for rings and other jewelry.”
