Common silver-based brazing alloys are often modified to reduce the melting point and cost by adding elements such as zinc, tin, or nickel, forming ternary or multicomponent alloys. For instance, adding nickel to silver brazing alloys improves their heat resistance, corrosion resistance, and wettability.
