Specific Gravity of Alloyed Metals - able2know

Feb 05, 2015 · I'd like to ask for some help regarding verifying the Specific Gravity of an alloyed metal, say a 22k gold chain, which gold content is supposed to be 91.6%. Pure Gold being 19.32 SG, a 91.6% pure item should be 91.6% of pure gold's SG, if I'm not mistaken. So a 22k gold item should be 17.70SG. Is this correct, or am I missing something? Thank you.
