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.

Maganin Rufewa

Ga tsarin hadawa na CuBe1.9 (1.8-2%), ana dumama hadin tsakanin 720°C da 860°C. A wannan lokacin, beryllium da ke cikinsa a zahiri yana "narkewa" a cikin matrix na jan ƙarfe (phase alpha). Ta hanyar rage saurin zuwa zafin ɗaki, wannan tsarin maganin mai ƙarfi yana riƙewa. Kayan da ke wannan matakin yana da laushi sosai kuma yana iya yin sanyi cikin sauƙi ta hanyar zane, ƙirƙirar birgima, ko kuma sanyaya kai. Aikin rage zafi wani ɓangare ne na aikin da ake yi a injin niƙa kuma ba a saba amfani da shi ta hanyar abokin ciniki ba. Zafin jiki, lokacin da ake amfani da shi a zafin jiki, saurin kashewa, girman hatsi, da tauri duk mahimman sigogi ne kuma TANKII ne ke sarrafa su sosai.

Taurarewar Shekaru

Taurarewar shekaru yana ƙara ƙarfin kayan sosai. Wannan amsawar galibi ana yin ta ne a yanayin zafi tsakanin 260°C da 540°C dangane da ƙarfe da halayen da ake so.
