Solution Hardening. One way to create metal alloys is solution hardening. Despite its complicated name, the concept of solution hardening is simple. Manufacturers will mix one metal with another to make a strong alloy. To do this, both metals must be in liquid form.

Why are alloys harder than pure metals?

Weballoys. 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.
