Babban Fasaha na Beryllium Copper (Maganin zafi)

Maganin zafi shine mafi mahimmancin tsari ga wannan tsarin ƙarfe. Duk da cewa dukkan ƙarfen jan ƙarfe ana iya taurare su ta hanyar aiki a sanyi, jan ƙarfe na beryllium ya keɓance ta hanyar amfani da maganin zafi mai sauƙi. Ya ƙunshi matakai biyu na asali. Na farko ana kiransa da maganin ruwa da kuma na biyu, ruwan sama ko taurarewar shekaru.
