Gold Alloys - an overview | ScienceDirect Topics

Gold alloys were initially used to fabricate archwires because they are inert, biocompatible, and stable. Furthermore, before the widespread use of the SS wire, gold alloys were used due to the lack of the availability of other materials that can tolerate the oral conditions. Gold wires are generally composed by of gold (15–65 wt.%), copper (11–15 wt.%), silver (10–25 wt.%), palladium (5 ...
