sed bħala materjali tal-ibbrejżjar prinċipali huma AgCu7.5, AgCu25, AgCu28,AgCu55, eċċ., U l-AgCu28 huwa użat ħafna. Huma għandhom konduttività tajba, fluwidità u tixrib, u tintuża ħafna fl-industrija tal-vakwu elettriku. Minħabba r-reżistenza baxxa għat-tagħbija fit-tul taħt temperatura għolja, huwa adattat biss għal partijiet tal-ibbrejżjar li t-temperatura tax-xogħol tagħhom hija inqas minn 400ºC.
Użat bħala muniti u dekorazzjonijiet. Il-ligi użati bħala muniti huma AgCu7.5, AgCu8,AgCu10, eċċ.; il-ligi użati bħala dekorazzjonijiet huma AgCu8.4, AgCu12.5, eċċ
