gold alloy
Mixed precious metal
A gold alloy is gold mixed with other metals to alter its properties—typically to increase hardness, durability, or to change its color.
Pure gold is soft and impractical for jewelry or coins, so it's commonly alloyed with copper, silver, zinc, or nickel.
The purity of gold alloys is measured in karats: 24-karat is pure gold, while 14-karat gold alloy contains about 58% gold.
