What is the Density of 10K 18K Gold? Answers

Aug 19, 20080183;32;Best Answer As you are probably aware, 10K gold is 10/24 (41.66%) gold, 14K gold is 14/24 (58.33%) and 18K 18/24 (75%) gold. However those designations do not specify what other metals make up the other part of the alloy. I am familiar with alloys with copper, silver, palladium, nickel, zinc, iron, or aluminum, and various combinations of these..
