Ana amfani da Beryllium Copper (UNS C17200) don kyakkyawan ƙarfin lantarki da ƙarfinsa. Yana iya aiki yadda ya kamata har zuwa kusan $400^{\circ}F$ ($204^{\circ}C$). Bayan wannan zafin jiki, kayan yana fara tsufa, yana haifar da saurin hasarar ƙarfin ƙarfi da na roba. A cikin masu haɗin lantarki, zoben yana aiki azaman na'urar riƙewa wanda kuma dole ne ya jure hawan keken zafi. Matsakaicin faɗaɗawar zafinta ($ α \kimanin 9.4 · 10 ^ {-6} / ^{\circ}F$) dole ne a daidaita shi da kayan gida don hana sassautawa a yanayin zafi. Ba kamar karfe ba, BeCu ba mai walƙiya ba ce kuma ba ta maganadisu ba, yana mai da shi manufa don yanayin yanayi maras tabbas.
