APPLICATIONS

TERNALLOY 7228 is a silver based eutectic alloy that due to its characteristics is widely used in the fields of electromechanical applications, especially in furnace brazing processes (Step brazing). It can also be used in welding processes involving flux. It can be used with copper and its nickel-based alloys and alloys; also with stainless steels although in this case the baganbility characteristics are reduced considerably. High temperature brazing (not exceeding 900 ºC) increases its fluidity and wettability characteristics
