Gold Alloys - an overview | ScienceDirect Topics

Gold–nickel–copper based white golds work-harden faster and are harder after annealing than gold–silver–copper-based yellow golds. These alloys are very susceptible to fire cracking when they are given a full anneal after light cold-working. White gold compositions are the result of a compromise between color and fire cracking tendency.
