Ngenkqubela phambili yenzululwazi yemathiriyeli, iirodi zobhedu ziphuhla zisiya ekusebenzeni okuphezulu kunye -nodibaniso olusebenzayo. Umzekelo, ubhedu oluphezulu-lwezinc (elinomxholo we-zinc ongaphezulu kwe-40%) luphucula ukuxhathisa ukubola ngokongeza izinto ezifana ne-nickel kunye ne-aluminiyam, igcina amandla ayo ngelixa iyenza ilungele iimeko zemizi-mveliso ezinzima. Inkokheli evumelana nokusingqongileyo -ibrasi yasimahla (efana ne-HWCuZn{7}}1), ngokusebenzisa ubuchwepheshe bokusebenzisa i-microalloying, ayithathi ndawo kuphela ilothe yemveli{9} equlathe ubhedu kodwa ikwagcina ukusebenza kakuhle, ukuhlangabezana neemfuno zokhuseleko lokusingqongileyo kushishino lombane kunye nombane. Ukongeza, ii-composites ezisekelwe kubhedu{10}(ezifana ne-brass{11}}i-graphite composite rods) zinciphisa ngakumbi i-coefficient of friction ngokongeza isigaba sokuthambisa, ebonisa amandla okusebenza kwiimeko zokunxiba okuphezulu okufana neebheringi kunye netywina.
