Materiae caudicae principales adhibitae sunt AgCu7.5,AgCu25, AgCu28, AgCu55, etc., et AgCu28 late usus est. Habent bonam conductivity, fluiditatem et wettability, et late in vacuo electrica industria utuntur. Propter humilitatem resistentiae longi temporis onus sub caliditate caliditatis, solum idoneus est ad partes aereas quarum operatio temperatura minor est quam 400ºC.
Usus est nummorum et ornamentorum. Admixti nummi sunt AgCu7.5, AgCu8;AgCu10, etc.; admixtiones pro ornamentis sunt AgCu8.4, AgCu12.5, etc
