sed mar phríomhábhair phrásála ná AgCu7.5, AgCu25, AgCu28,AgCu55, etc., agus tá an AgCu28 úsáid go forleathan.Tá seoltacht maith, fluidity agus wettability, agus úsáidtear go forleathan sa tionscal bhfolús leictreach. Mar gheall ar an fhriotaíocht íseal ar ualach fadtéarmach faoi theocht ard, níl sé oiriúnach ach le haghaidh páirteanna prásála a bhfuil a dteocht oibre níos ísle ná 400ºC.
Úsáidte mar bhoinn agus maisiúcháin. Is iad na cóimhiotail a úsáidtear mar bhoinn ná AgCu7.5, AgCu8,AgCu10, srl; is iad na cóimhiotail a úsáidtear mar mhaisiúcháin ná AgCu8.4, AgCu12.5, etc
