Therefore, metals such as Silver, Bronze, and zinc are usually added to gold to increase its strength and toughness. The alloy is called "karat gold". The gold content in K gold is usually expressed in K numbers, 24K is pure gold, that is, the gold content is 99.9% pure (there is no 100% pure gold jewelry), 18K gold content is 75% (18/24), 14K is 58.5% (14/24), 10K is 41.7% (10/24), and so on.
