Nickel ua npuas ncauj tuaj yeem siv los ua cov khoom siv lim dej, cov khoom siv sib nqus sib nqus rau kev soj ntsuam nrog cov khoom sib nqus hauv cov kua dej. Lwm daim ntawv thov suav nrog daim ntawv thov rau hydrogen cia predicates thiab tshav kub pauv predicates. Nickel ua npuas ncauj yog cov khoom siv suab nrov nrog kev ua haujlwm zoo, uas muaj lub suab nrov-absorbing coefficient ntawm high zaus; nws lub suab-absorbing kev ua tau zoo ntawm tsawg zaus tuaj yeem ua tiav los ntawm kev tsim cov suab-absorbing qauv. Nickel ua npuas ncauj kuj yog ib qho ntawm cov khoom siv hluav taws xob zoo rau kev ua cov roj teeb cadmium-nickel thiab hydrogen-nickel roj teeb. Cov txheej txheem ntawm kev npaj nickel ua npuas ncauj los ntawm cov txheej txheem electro-deposition tau ua tiav los ntawm kev sim. Lub hauv paus khoom siv yog ntxeem tau qhib-cell ua npuas ncauj yas. Cov txheej txheem conductive tuaj yeem npaj tau los ntawm peb txoj kev: tshuaj lom neeg nickel plating, nqus nickel plating thiab immersion conductive nplaum. Tom qab ua ntej nicking, nws tuaj yeem raug plated hauv cov tshuaj sulfate nickel plating. Nickel, tom qab hlawv, rov qab thiab txheej txheem annealing, tuaj yeem tau cov khoom siv nickel ua npuas ncauj nrog kev ua haujlwm zoo.
