Ngokuthuthuka kwesayensi yezinto, ama-brass rods athuthukela ekusebenzeni okuphezulu kanye{0}}nokuhlanganiswa kwemisebenzi eminingi. Isibonelo, -ithusi eliphezulu le-zinc (elinokuqukethwe kwe-zinc engaphezu kuka-40%) lithuthukisa ukumelana nokugqwala ngokungeza izakhi ezifana ne-nickel ne-aluminium, igcina amandla ayo kuyilapho iyenza ifanelekele izindawo eziqinile zezimboni. Ukuhola evumelana nemvelo{5}}okufana ne-HWCuZn-1), ngobuchwepheshe be-microalloying, akugcini nje kuphela esikhundleni somthofu wendabuko-oqukethe ithusi kodwa futhi igcina ukusebenza kahle kakhulu, ehlangabezana nezimfuneko zokuvikela imvelo ze-electronics kanye nemboni kagesi. Ngaphezu kwalokho, ama-composites{10}esekelwe ethusi (njengethusi{11}}njengama-graphite composite rods) aqhubeka enciphisa i-coefficient of friction ngokungeza isigaba sokuthambisa, okubonisa amandla okusebenza ezimweni zokugqoka okuphezulu njengamabheringi nama-seal.
