Ekukhetheni izinto zoshishino, umbuzo oqhelekileyo ovela kubathengi uthi, “Yeyiphi engcono, yi-nickel okanye yi-copper?” Nangona kunjalo, enyanisweni, akukho “ngcono” ngokupheleleyo, kuphela “ifanelekileyo ngakumbi”—i-nickel igqwesile ekumelaneni nokugqwala kunye nokumelana nobushushu obuphezulu, ngelixa i-copper inika amandla aphezulu ombane kunye nokusebenza kakuhle kweendleko. Ngayinye idlala ngamandla ayo kwiimeko ezahlukeneyo. Ukuqala kwiipropati eziphambili, amasimi okusetyenziswa, kunye nokusetyenziswa okusebenzayo, eli nqaku liza kukunceda ucacise ingqiqo yokukhetha phakathi kwe-nickel kunye ne-copper, ikwenze ufumane isisombululo sezinto ezifanelekileyo kwiimfuno zakho.
Okokuqala, itheyibhile engezantsi inika uthelekiso olucacileyo lweempawu eziphambili kunye nezikhokelo zokuziqhelanisa phakathii-nickel(ngokusekelwe kwiimveliso zethu ze-nickel ezicocekileyo, ezinobunyulu obuyi-≥99.95%) kunyeithusi(ubhedu olucocekileyo lwemizi-mveliso, olunobunyulu obuyi-≥99.9%):
| Umlinganiselo wokuthelekisa | I-Nickel (Izinto zeNickel ezicocekileyo) | Ubhedu (Ubhedu olucocekileyo lwemizi-mveliso) | I-Core Adaptation Logic |
| Ukuqhuba kombane | Ukuqhuba: 22.1×10⁶ S/m | Ukuqhuba: 58.5×10⁶ S/m (phantse iphindwe ka-2.6 kune-nickel) | Khetha ithusi kwiimeko eziqhelekileyo zokuqhuba; khetha i-nickel kwiimeko zokuqhuba ezifuna zombini ukumelana nokugqwala/ukumelana nobushushu obuphezulu |
| Ukumelana nokugqwala | Ayinawo umhlwa kwiiasidi, iialkali, kunye nokugqwala komzimba (ihambelana nomgangatho we-ISO 10993), ayinawo umhlwa emva kokungena emanzini olwandle iiyure ezili-1000 | Ilungele ukubola kunye nokwakheka kwe-patina, ukumelana ne-asidi ebuthathaka/i-alkali, ifanelekile kuphela kwiindawo ezomileyo/ezinobuthi obuncinci | Khetha i-nickel kwiindawo ezirhabaxa (ishishini leekhemikhali, unyango, ulwandle); khetha ubhedu kwiindawo ezomileyo neziqhelekileyo |
| Ukumelana nobushushu obuphezulu | Indawo yokunyibilika: 1455℃, ubushushu benkonzo yexesha elide ukuya kuthi ga kwi-1200℃ | Indawo yokunyibilika: 1083℃, ubushushu benkonzo yexesha elide ≤300℃ | Khetha i-nickel kwiimeko zobushushu obuphezulu (izixhobo zokufudumeza, i-aerospace); khetha ubhedu kwiimeko zobushushu obuphantsi/ubushushu begumbi |
| Ubuchule bokusebenza kunye nokuqhubekeka | Ukuqina okuhle kobushushu obuphantsi (kunokugotywa kwi -200℃), kunokutsalwa kwiingcingo ezicolekileyo kakhulu ze-0.05mm | Ukuguquguquka okugqwesileyo, kulula ukuyinyathela nokuyigoba, ixabiso eliphantsi lokucubungula | Khetha i-nickel kwiinkcukacha ezikumgangatho ophantsi kakhulu/ezincinci kakhulu; khetha i-copper kwiimfuno ezintsonkothileyo/ezingabizi kakhulu |
| Iifom zeMveliso eziqhelekileyo | Ucingo lwe-nickel olucocekileyo, umcu we-nickel alloy, i-foil ye-nickel | Ucingo lwekopolo, ibha yebhasi yekopolo, ifoyile yekopolo | Hlanganisa uhlobo lwemveliso neemfuno zemeko; sibonelela ngokwezifiso ze-nickel/copper-nickel alloys |
Ngokwembono yeemeko zesicelo esisebenzayo, umahluko ekukhetheni phakathi kwezi zimbini ucacile nangakumbi:
Kwicandelo lokuqhuba nge-elektroniki, i-copper ikhethwa kakhulu kwiingcingo zezixhobo zasekhaya kunye neentambo ze-voltage ephantsi—iyahlangabezana neemfuno ezisisiseko zokuqhuba nge-conductivity ephezulu kunye nexabiso eliphantsi. Nangona kunjalo, i-nickel iyimfuneko kwiingcingo zangaphakathi zezixhobo zonyango (umz., iintambo ze-glucose pen probe) kunye neengcingo zesignali yezixhobo ze-aerospace: yokuqala ifuna ukumelana nokugqwala kolwelo lomzimba, ngelixa yokugqibela ifuna ukumelana nobushushu obuphantsi (ngaphantsi kwe--50℃ kwiindawo eziphakamileyo). Iingcingo zethu ze-nickel ezicocekileyo ezenziwe ngokwezifiso ezinokunyamezela kwe-0.002mm ziye zahlengahlengiswa ngamashishini amaninzi ezonyango/e-aerospace.
Kwiimeko ezimelana nokugqwala, i-nickel (hayi ithusi) ikhethwa kwiilinki zetanki zokugcina iikhemikhali kunye nezihlanganisi zezixhobo zaselwandle: ithusi liyagqwala kwisithuba senyanga enye emanzini anetyuwa okanye kwiindawo ezineasidi, ngelixa iilinki zetanki zokugcina ezenziwe ngeepleyiti zethu ze-nickel ezicocekileyo zihlala zingavuzi emva kweminyaka emi-3 yokusetyenziswa kwiinkampani zeekhemikhali. Nangona kunjalo, ithusi linenzuzo ecacileyo yokusebenzisa iindleko kwiimhombiso zezakhiwo kunye nezihlanganisi ngokubanzi kwiindawo ezomileyo.
Kwizicelo zobushushu obuphezulu, yi-nickel kuphela enokusetyenziselwa ukufudumeza izinto zezixhobo zokufudumeza kunye neengcingo zeenzwa zokukhupha umoya zeemoto: ubhedu luyathamba kwaye luguquguquke kumaqondo obushushu angaphezu kwama-500℃, ngelixa izinto zokufudumeza ezenziwe ngeengcingo zethu ze-nickel ezicocekileyo zinokusebenza ngokuzinzileyo kwi-1200℃ kwii-oven zoshishino ngaphezulu kweeyure ezingama-5000. Ukufudumeza kumaqondo obushushu egumbi (umz., izifudumezi zamandla aphantsi kwizixhobo zasekhaya), ubhedu lunokukhethwa ukunciphisa iindleko.
Okuphawulekayo kukuba, xa imeko ifuna “ukuqhuba kobhedu + ukumelana nokugqwala kwe-nickel,” iimveliso zethu ze-copper-nickel alloy (umz., i-CuNi40) zezona zisombululo zifanelekileyo—zigcina inzuzo yokuqhuba kobhedu (ukuqhuba: 15×10⁶ S/m) ngelixa zinokumelana nokugqwala kwe-nickel (ukumelana nokugqwala kwamanzi olwandle okufana nokwe-nickel ecocekileyo), kwaye zisetyenziswa kakhulu kwiintambo zaselwandle nakwizixhobo zokususa ityuwa emanzini olwandle.
Ngamafutshane, isitshixo sokukhetha phakathi kwe-nickel kunye ne-copper sixhomekeke "kukuba kufuneka ukumelana nokugqwala, ukumelana nobushushu obuphezulu, okanye ukumelana nobushushu obuphantsi kakhulu": ukuba ezi mpawu ziyafuneka, i-nickel lukhetho oluthembekileyo ngakumbi; ukuba kufuneka kuphela ukuhanjiswa kwe-conductivity esisiseko, iindleko eziphantsi, kunye nokucutshungulwa okulula, i-copper ifanelekile ngakumbi. Ukuba awuqinisekanga malunga nokukhetha izinto, nceda uzive ukhululekile ukunxibelelana nathi—singabonelela ngeesampuli ezenzelwe wena ze-nickel, i-copper, kunye ne-copper-nickel alloys zingadlulanga iiyure ezingama-72 ngokusekelwe kwiiparameter zakho zesimo (umz., ubushushu, i-medium, iimfuno zokuhanjiswa kwe-conductivity),ukukunceda ulungelelanise ngokuchanekileyo isisombululo sezinto ezibonakalayo.
