Fa'atauga mama po'onikeli fa'afefiloi maualalomaua lona aoga autu i le gaosiga o vailaau ma mea tau eletise.
Tete'e a'e
Ona o le mama o le nickel's corrosion resistance, aemaise lava i vailaʻau faʻaitiitiga eseese aemaise lava i alkalis caustic, o loʻo faʻaaogaina le nickel e faʻamautu ai le lelei o oloa i le tele o vailaʻau faʻainisinia, aemaise le gaosiga o meaʻai ma le gaosiga o fiber synthetic.
Meatotino o Nikeli Mama Faapisinisi
Pe a faatusatusa iu'amea nikeli, nickel mama faapisinisi ei ai conductivity eletise maualuga, se vevela Curie maualuga ma meatotino magnetostrictive lelei. O le nikeli e fa'aoga mo uaea fa'aeletonika, vaega o le maa, thyratrons ma fa'aeletise fe'ai.
E lelei fo'i le fa'avevelaina o le vevela o le nikeli. O lona uiga e mafai ona fa'aoga mo fa'afesuia'i vevela i si'osi'omaga pala.

Fausiaina o nikeli
Fa'amauinanikelie maualalo le maaa ma lelei ductility. Nikeli, pei o le auro, siliva ma le kopa, e maualalo le fua o le fa'ama'a'aina o galuega, o lona uiga e le ma'a'a ma ma'a'a'a pe a punou pe fa'aletonu e pei o le tele o isi metala. O nei uiga, tu'ufa'atasia ma le lelei lelei, e fa'afaigofie ai le fa'apipi'iina o le u'amea i mea ua mae'a.
Nikeli i Chromium Plating
E masani fo'i ona fa'aogaina le nikeli e fai ma 'ofu lalo i le fa'apalapala o le chromium teuteu. O le oloa mata, e pei o se apamemea po'o se fa'amea fa'asala po'o se u'amea u'amea oomi e muamua fa'apipi'i i se vaega onikelie tusa ma le 20µm mafiafia. O le mea lea e maua ai lona tete'e i le pala. O le peleue fa'ai'u o se 'momi' manifinifi (1-2µm) o le chromium e maua ai se lanu ma fa'afefeteina e masani ona manatu e sili atu ona mana'omia i mea fa'apipi'i. O le Chromium na'o le a le taliaina le pala ona o le natura masani o le porous o le chromium electroplate.
