Nickel ndi chitsulo cholimba, chodulira, komanso ferromagnetic chomwe chimapukutidwa kwambiri komanso chosachita dzimbiri. Nickel ndi gulu la zinthu zokonda chitsulo. Pakatikati pa dziko lapansi pali zinthu zambiri zachitsulo ndi faifi tambala. Miyala ya iron magnesium mu kutumphuka imakhala ndi faifi tambala kuposa miyala ya silicon aluminiyamu, mwachitsanzo, peridotite imakhala ndi faifi ya chitsulo nthawi 1000 kuposa granite, ndipo gabbro imakhala ndi faifi wochulukira nthawi 80 kuposa granite.

Mankhwala amatha kugwira ntchito, koma okhazikika kuposa chitsulo. Zovuta kuti oxidize mu mpweya firiji osati mosavuta anaikira nitric asidi. Waya wa faifine faifi amatha kuyaka ndipo amakumana ndi ma halojeni akatenthedwa, kusungunuka pang'onopang'ono mu asidi wosungunuka. Imatha kuyamwa mpweya wambiri wa haidrojeni.
