Monga tonse tikudziwa, mkuwa ndi faifi tambala ndi zinthu ziwiri zomwe zimagwiritsidwa ntchito kwambiri padziko lonse lapansi zazitsulo ndi ma aloyi. Akaphatikizidwa, amapanga alloy yapadera yotchedwa copper-nickel, yomwe ili ndi zake komanso ntchito zake. Zakhalanso mfundo yochititsa chidwi m'maganizo a ambiri ngati nickel yamkuwa ili ndi phindu lililonse pazantchito zothandiza komanso mtengo wamsika. M'nkhaniyi, tidzakambirana nanu za katundu ndi ntchito za mkuwa-nickel, komanso mtengo wake pazochitika zachuma.
Monga tafotokozera kale, nickel yamkuwa ndi alloy yomwe imakhala ndi 70-90% yamkuwa ndi 10-30% ya faifi tambala. Kuphatikizika kwa zinthu ziwirizi kumapangitsa kuti zinthuzo zisamawonongeke kwambiri, kutenthetsa ndi magetsi, kupangitsa kuti faifi ya mkuwa ikhale yofunika kwambiri pamafakitale osiyanasiyana.
Chimodzi mwazinthu zomwe zimagwiritsidwa ntchito ndi aloyi amkuwa ndi nickel ndikupanga ndalama. Mayiko ambiri amagwiritsa ntchito ma alloys a copper-nickel popanga ndalama zachitsulo chifukwa cha kulimba kwawo komanso kukana dzimbiri. Kuphatikiza pa ndalama zachitsulo, nickel yamkuwa imagwiritsidwa ntchito popanga zinthu zam'madzi monga zombo zapamadzi,osinthanitsa kutenthandi zida zochotsera mchere, zomwe zimakhala ndi kukana kwa dzimbiri m'madzi amchere. Mapangidwe apamwamba amagetsi amkuwa-nickel amapangitsa kukhala chinthu chosankha kupanga mawaya, zolumikizira ndi zida zina zamagetsi m'munda waukadaulo wamagetsi. Kutentha kwamafuta amkuwa-nickel kumapangitsanso kuti ikhale yoyenera kutenthaosinthanitsandi ntchito zina zotengera kutentha.
Kuchokera pakuwona msika, mtengo wa nickel wamkuwa umakhudzidwa ndi zinthu zingapo, kuphatikizapo, koma osati, zofuna za msika wamakono, kupezeka kwapadziko lonse, ndi mitengo yomwe ilipo yamkuwa ndi faifi tambala. Monga momwe zilili ndi chinthu chilichonse, mtengo wa mkuwa ndi faifi umasinthasintha potengera izi. Otsatsa malonda ndi amalonda amayang'anitsitsa zomwe zikuchitika pamsika kuti awone phindu la mkuwa ndi faifi tambala komanso kupanga zisankho zabwino pazamalonda ndi ndalama zawo.
M'zaka zaposachedwa, matekinoloje amphamvu zongowonjezwdwanso, makamaka kupanga ma solar panels ndi ma turbines amphepo, alikulimbikitsakufunikira kwa nickel yamkuwa. Ndikusintha kwapadziko lonse lapansi kumayendedwe okhazikika amagetsi, kufunikira kwa nickel yamkuwa kukuyembekezeka kukwera, zomwe zingakhudze mtengo wake wamsika.
Kuonjezera apo, ndondomeko zamalonda zingakhudzenso mtengo wa nickel-copper. Misonkho, mapangano amalonda amatha kukhudza mayendedwe ndi mitengo ya nickel-copper, zomwe zimapangitsa kusinthasintha kwamtengo wake wamsika. Choncho, ogwira nawo ntchito m'makampani amkuwa ndi nickel amayang'anitsitsa zinthu zakunja izi kuti athe kuyembekezera kusintha kwa mtengo wachitsulo.
Pankhani ya umwini, anthu amatha kukumana ndi nickel yamkuwa m'njira zosiyanasiyana, monga ndalama zachitsulo, zodzikongoletsera kapena zinthu zapakhomo. Ngakhale kuti mtengo wamtengo wapatali wa nickel wa mkuwa muzinthuzi ukhoza kukhala wotsika, mbiri yakale kapena mtengo wamaganizo womwe umagwirizanitsidwa nawo ukhoza kuwapangitsa kukhala oyenera kusungidwa kapena kusonkhanitsa. Mwachitsanzo, ndalama zosowa kapena zachikumbutso zopangidwa kuchokera ku ma aloyi a nickel-copper-nickel zitha kukhala zamtengo wapatali kwa otolera chifukwa chakuchepa kwawo komanso mbiri yawo.
Mwachidule, ma alloys amkuwa-nickel ali ndi phindu lalikulu pazogwiritsa ntchito komanso pamsika. Makhalidwe ake apadera amachititsa kuti ikhale yofunidwa m'mafakitale osiyanasiyana, kuchokera ku ndalama kupita ku mphamvu zowonjezera. Mtengo wamsika wamkuwa-nickel umasinthasintha ndi zinthu zosiyanasiyana zachuma ndi mafakitale. Kaya ndi gawo lofunikira kwambiri pantchito zamafakitale kapena ngati chinthu chosonkhanitsa, faifi ya mkuwa imakhala ndi gawo lofunikira pachuma chapadziko lonse lapansi komanso m'moyo watsiku ndi tsiku.
