... Laves phase that melts congruently at 1219 °C (2225 °F). The gamma phase melts peritectically at 930 °C (1705 °F) and has a CsCl ordered cubic structure. The beta phase is a disordered solid solution stable above 620 °C (1150 °F). The solid solubility of beryllium in copper is sufficient to yield useful...

... of these alloys as wrought products is difficult and the joints formed using them tend to be weak. Hence, they are seldom used industrially. This weakness is accounted for by the phase relationships in this ternary alloy system. For alloys of silver and copper containing up to about 25% zinc, the major phases...
