Answer
An zaɓi Beryllium Copper (yawanci Alloy C17200) don maɓuɓɓugan ruwan raƙuman ruwa waɗanda ke buƙatar haɓakar wutar lantarki da abubuwan da ba na maganadisu ba. Yana da wutar lantarki na $15$-$25\%$ IACS, wanda ya wuce bakin karfe. A cikin garkuwar EMI, igiyar igiyar ruwa tana samar da wuraren tuntuɓar juna da yawa don tabbatar da ƙarancin rashin ƙarfi zuwa ƙasa. A inji, CuBe za a iya taurare zuwa matakan kwatankwacin da alloy karfe (har zuwa $200 $ ksi tensile ƙarfi). Koyaya, sarrafawa ya ƙunshi warwarewar warwarewa sannan taurin hazo a $600^{\circ}F$ na awanni 2-3. Dole ne injiniyoyi su yi lissafin ƙananan Modulus na Ƙarfafawa ($ E \ Kimanin 124$ GPa), wanda ke buƙatar abu mai kauri ko ƙarin raƙuman ruwa don cimma nauyi iri ɗaya da maɓuɓɓugar ƙarfe mai girma iri ɗaya.
