Answer
Beryllium Copper (CuBe) Alloy 25 (UNS C17200) shine mafi girman ƙarfi na tushen tagulla. Ana amfani da shi don zoben karkace a cikin mahalli masu fashewa (marasa haskakawa) da kuma a cikin na'urorin lantarki masu mahimmanci ko na'urorin MRI (mara magnetic, μ <1.001). Za a iya ɗora zoben CuBe shekaru don cimma ƙarfin juriya har zuwa 1400 MPa, kwatankwacin ƙarfe da yawa. Koyaya, Modulus na Elasticity $ E$ yana ƙasa ($ ≈$ 125 GPa idan aka kwatanta da 200 GPa don ƙarfe), ma'ana zoben CuBe suna ba da ƙarancin tashin hankali don kauri ɗaya. Dole ne injiniyoyin ƙira su ƙididdige gubar ƙurar beryllium yayin kowane injin da ke gaba, kodayake ƙãrewar zoben ba shi da lafiya don amfani.
