Me ka holomua ʻana o ka ʻepekema waiwai, ke ulu nei nā koʻokoʻo keleawe i ka hana kiʻekiʻe a me ka hoʻohui -nui. No ka laʻana, ʻoi aku ka -zinc keleawe kiʻekiʻe (me ka zinc ma luna o 40%) i kona kūpaʻa ʻana i ka corrosion ma o ka hoʻohui ʻana i nā mea e like me ka nickel a me ka aluminika, e mālama ana i kona ikaika ʻoiai e kūpono ana ia no nā wahi ʻoihana ʻoi aku ka paʻakikī. ʻAʻole hoʻololi wale ke kēpau kuʻuna -keleawe like ʻole (e like me HWCuZn-1), ma o ka ʻenehana microalloying, akā mālama pū nō hoʻi i ka machinability maikaʻi loa, e kū ana i nā koi palekana o ka ʻoihana uila a me ka ʻoihana uila. Eia kekahi, ʻo nā hui keleawe -composite (e like me ke keleawe-graphite composite rods) e hoʻemi hou i ka coefficient o ka friction ma o ka hoʻohui ʻana i kahi pae lubricating, e hōʻike ana i ka hiki ke hoʻohana ʻia i nā hiʻohiʻona lole kiʻekiʻe e like me nā bearings a me nā sila.
