Mzere wa Cupronickel ndi aloyi ya mkuwa yokhala ndi nickel ngati chinthu chachikulu chopangira aloyi. Mizere ya mkuwa-nickel yochokera ku aloyi ya mkuwa-nickel yokhala ndi zinthu zachitatu monga zinc, manganese, aluminiyamu, ndi zina zotero zimatchedwa mizere ya zinc-nickel-nickel, mizere ya manganese-nickel-nickel, ndi mizere ya aluminiyamu-nickel-nickel moyenerera. Aloyi ya mkuwa-nickel ili ndi kukana dzimbiri bwino, mphamvu yapakati, pulasitiki wambiri, ndipo imatha kukonzedwa ndi kutentha ndi kuzizira.
Mizere yoyera yamkuwa imagawidwa m'magulu asanu: mizere yoyera yamkuwa wamba, mizere yoyera yamkuwa yachitsulo, mizere yoyera yamkuwa ya manganese, mizere yoyera yamkuwa ya zinc ndi mizere yoyera yamkuwa ya aluminiyamu.
Mizere yoyera ya mkuwa wamba imakhala ndi mitundu inayi ya alloy monga B0.6, B5, B19, ndi B30. Yomwe imagwiritsidwa ntchito kwambiri ndi B19 ndi B30, ndipo pali mitundu yambiri mu mndandanda wa American standard. Mzere woyera wa mkuwa ndi yankho lolimba lopangidwa ndi Cu ndi Ni, lokhala ndi lattice yozungulira nkhope, monga momwe zasonyezedwera pa Chithunzi 1-18. Pamene kutentha kuli kotsika kuposa madigiri 322, chithunzi cha gawo la mkuwa ndi nickel chimakhala ndi dera lalikulu la kutentha kwa kapangidwe kake komwe kamawonongeka mosavuta, kuwonjezera zinthu zachitatu monga Fe, Cr, Sn, Ti, Co, Si, Al ku Cu-Ni alloy Etc., imatha kusintha kapangidwe kake, kutentha komwe kumawonongeka komanso malo ake, komanso imatha kusintha zina mwa zinthu za alloy. Mbale yoyera yamba wamba imakhala ndi ntchito yabwino yozizira komanso yotentha. Itha kukonzedwa bwino m'mawonekedwe osiyanasiyana monga mbale, mipiringidzo, machubu, ndodo, mawonekedwe, ndi mawaya. Kuchita bwino kwa welding, kungagwiritsidwe ntchito popangira brazing yofewa komanso yolimba, welding ya arc yotetezedwa ndi gasi komanso welding yokana, ndi zina zotero; Kudula bwino ndi 20% ya HPb63-3 yamkuwa yodulidwa momasuka. Mbale ya mkuwa yoyera wamba imakhala ndi kukana dzimbiri, mphamvu yapakati, pulasitiki wambiri, imatha kukonzedwa ndi kutentha ndi kuzizira, komanso mphamvu zamagetsi zabwino. Kuwonjezera pa kugwiritsidwa ntchito ngati zinthu zomangira, ndi aloyi yofunika kwambiri yokana kwambiri komanso thermocouple.
