Silver processing - The metal and its alloys Britannica
Silver processing - Silver processing - The metal and its alloys: Even silver that has been fully work-hardened, either by rolling or forging, gradually recrystallizes, even at room temperature. This greatly softens the metal, making it susceptible to scratching and marring. To maintain hardness, therefore, other metals are added to form alloys that are harder, stronger, and less prone to fatigue.
