Berylium jan ƙarfe-tushen alloy dauke da berylium (be0.2 ~ 2.75% wt%), wanda aka yi amfani dashi sosai a duk allolin beryllium.
Amfani ya wuce kashi 70% na yawan amfani da berylium a cikin duniya a yau. Berylium Taya shine hazo hardening Sundering, wanda ke da ƙarfi mai ƙarfi, da taurin kai, iyaka na roba da ga iyaka na tsufa, kuma yana da karamin hysteresis.
Kuma yana da juriya na lalata (lalata lalata ƙwayar cuta na ƙarfe Alloy cikin bakin ruwa: (1.1-1.4) × 10-2Sm 10.8.) Bayan lalata Alloy, farashin elongation bashi da canji, saboda haka ana iya kiyayewa fiye da shekaru 40 a cikin dawowar ruwa,
Berylium Fory BeryLoy abu ne wanda ba za a iya warware shi ba don tsayar da tsarin maimaitawa.
A cikin matsakaici: zurfin lalata na shekara-shekara zurfin berylium a wani maida ƙasa da 80% (a dakin zazzabi) shine 0.0012 zuwa 0.1175mm, kuma maida hankali ne da 80%. Saka juriya, karancin zazzabi, rashin sihiri, babban aiki, tasiri kuma babu turke. A lokaci guda, yana da kyawawan launuka da ikon yin samfuran lafiya. Saboda yawancin kaddarorin beryllium jan ƙarfe na beryllium, an yi amfani da shi sosai a masana'antu.
