Mtengo wa Nickel:kukhazikika kwamphamvu kwamankhwala komanso kukana kwa dzimbiri m'ma media ambiri. Ma electrode ake okhazikika ndi -0.25V, omwe ali abwino kuposa chitsulo komanso olakwika kuposa mkuwa.Nickel amawonetsa kukana kwa dzimbiri pakalibe mpweya wosungunuka muzinthu zopanda oxidized (mwachitsanzo, HCU, H2SO4), makamaka munjira zopanda ndale komanso zamchere. .Izi ndi chifukwa faifi tambala ali ndi mphamvu passivate, kupanga wandiweyani zoteteza filimu pamwamba, amene amalepheretsa faifi tambala kupitirira makutidwe ndi okosijeni.
Ntchito:
Itha kugwiritsidwa ntchito popangira magetsi otenthetsera zinthu mu zida zotsika-voltage, monga matenthedwe owonjezera, otsika-voltage circuit breaker, ndi zina zotero. Ndipo amagwiritsidwa ntchito posinthanitsa ndi kutentha kapena machubu a condenser mu evaporators of desalination plant, process industry planter, air madera ozizira a malo opangira magetsi otentha, zotenthetsera madzi othamanga kwambiri, komanso mipope yamadzi am'nyanja m'zombo.
