Included in this group are also the silver bronzes (CuAg) with 2 – 6 wt% of Ag. Copper-Zinc Alloys Test (Brasses) Copper-zinc alloys are widely used as contact carrier materials in switching devices for electrical power engineering because of their high electrical conductivity, the higher mechanical strength combined with good formability ...
