Nickel 200 (UNS N02200) ndi 201 (UNS N02201) ndi zida za faifi wopangidwa pawiri-certifiable. Amasiyana pamlingo wokwanira wa kaboni womwe ulipo - 0.15% pa Nickel 200 ndi 0.02% pa Nickel 201.
Mbale ya Nickel 200 nthawi zambiri imakhala yogwira ntchito pa kutentha kosachepera 600ºF (315ºC), chifukwa kutentha kwapamwamba kumatha kuvutika ndi graphitization yomwe imatha kusokoneza kwambiri katundu. Pakutentha kwambiri, mbale ya Nickel 201 iyenera kugwiritsidwa ntchito. Magiredi onsewa amavomerezedwa pansi pa ASME Boiler ndi Pressure Vessel Code Gawo VIII, Gawo 1. Mbale ya Nickel 200 imavomerezedwa kuti igwiritsidwe ntchito mpaka 600ºF (315ºC), pomwe mbale ya Nickel 201 imavomerezedwa mpaka 1250ºF (677ºC).
Maphunziro onsewa amapereka kukana kwa dzimbiri kwa caustic soda ndi ma alkali ena. Ma alloys amachita bwino kwambiri pochepetsa malo koma amatha kugwiritsidwanso ntchito pansi pamikhalidwe yotulutsa okosijeni yomwe imatulutsa filimu ya passive oxide. Onsewa amakana dzimbiri ndi madzi osungunula, achilengedwe komanso madzi a m'nyanja oyenda koma amawukiridwa ndi madzi a m'nyanja osasunthika.
Nickel 200 ndi 201 ndi ferromagnetic ndipo amawonetsa ma ductile makina pamakina osiyanasiyana kutentha.
Makalasi onsewa amawokeredwa mosavuta ndikukonzedwa ndi njira zopangira masitolo.
