Hello Ian,

Alloys with small amounts of gold can certainly oxidize, but I think it is the copper or silver components that are most affected by the oxidation.

Yes, in gold alloys it is the "lower" metals which oxidize while the gold is quite inert in such a setting.

However, alloys can exhibit quite a few funny/weird characteristics which need in-depth research to really appreciate them fully.

Regards,
Kai
