The copper atom is significantly smaller than that of gold and so it has a greater effect on strengthening gold than silver, as it distorts the gold crystal lattice more. Thus reducing karatage from 24 karats through 22 kt down to 18 karat gold results in stronger and harder alloys, but alloying beyond 18 kt down to 9 karat does not have much ...
