Xa kukhangelwa into ebambeleyoucingo lwe-nichrome, kubalulekile ukuqwalasela iimpawu eziphambili ezenza i-nichrome ibaluleke kakhulu: ukumelana nobushushu obuphezulu, ukuxhathisa umbane okungaguqukiyo, ukuxhathisa ukubola, kunye nokuqina. Ngelixa izixhobo ezininzi zisondele, akukho nto ihambelana nebhalansi ekhethekileyo yokusebenza kwe-nichrome-ukwenza iimveliso zethu zocingo lwe-nichrome zibe lukhetho oluthembekileyo kwizicelo ezibalulekileyo.
Enye indlela eqhelekileyo yi-kanthal wire, iintsimbi-chromium-aluminiyam ingxubevange. I-Kanthal igqwesa kwiindawo eziphakamileyo zokushisa, ukumelana nokushisa ukuya kwi-1,400 ° C, ephakamileyo kunamabakala athile e-nichrome. Nangona kunjalo, inkuthe-mbuke ngakumbi kwaye ayinyangeki kangako, nto leyo eyenza kube nzima ukuyimilisela kwiindlela zoyilo ezintsonkothileyo. Kwizicelo ezifuna ukuguquguquka, njengezinto ezincinci zokufudumeza kwi-electronics, i-kanthal ihlala imfutshane, ngelixa i-ductility ye-nichrome ivumela ukubunjwa okuchanekileyo ngaphandle kokuqhekeka.
I-Copper-nickel (i-Cu-Ni) yocingo yenye i-contender, ixabiswa ngenxa yokumelana nokugqwala kunye nokumelana okuphakathi. Kodwa i-Cu-Ni iyazabalaza kumaqondo obushushu aphezulu, i-oxidizing ngokukhawuleza ngaphezu kwe-300 ° C, ethintela ukusetyenziswa kwayo kwiimeko zokushisa okuphezulu njengeziko zoshishino okanye iikhoyili zokufudumeza. I-Nichrome, ngokuchaseneyo, igcina uzinzo nakwi-1,200 ° C, iyenza ibe yinto eguquguqukayo kakhulu kwimisebenzi yobushushu obuphezulu.
Ucingo lweTungsten lubonelela ngokuxhathisa ubushushu, ukumelana nobushushu obugqithisileyo ukuya kuthi ga kwi-3,422°C. Nangona kunjalo, i-brittle kakhulu kwaye ine-resistivity ephantsi yombane, ifuna imisinga ephezulu ukwenza ubushushu. Oku kwenza ukuba kungenzeki kwizicelo ezininzi zokufudumeza apho ukusetyenziswa kwamandla kunye nokulula kokusetyenziswa kwezinto-iindawo apho i-nichrome, kunye nokumelana kwayo okufanelekileyo kunye nokusebenza, ikhanya.
I-stainless steel wire idla ngokuqwalaselwa ukufikeleleka kwayo kunye nokuxhathisa ukubola. Nangona kunjalo, inokumelana okuphantsi kune-nichrome, oku kuthetha ukuba ivelisa ubushushu obuncinci ngobude beyunithi, ifuna i-gauges ethe kratya okanye i-voltages ephezulu ukuhambelana nokuphuma kwe-nichrome. Ngokuhamba kwexesha, intsimbi engatyiwayo ithande ukonakala phantsi kobushushu obude, inciphisa ubomi bayo xa ithelekiswa nokuzinza kwexesha elide le-nichrome.
Iimveliso zethu zocingo lwe-nichrome zijongana nale mida yokuthatha indawo. Ifumaneka kumabakala ahlukeneyo (afana neNiCr 80/20), banikezela ngokuchaneka kokuchaneka kwemveliso yobushushu engaguqukiyo, i-ductility egqwesileyo yokwenza lula, kunye nokumelana okuphezulu kwe-oxidation kumaqondo aphezulu. Nokuba zezokufudumala izinto kwizixhobo zombane, izixhobo zaselabhorethri, okanye kwiziko loshishino, ucingo lwethu lwe-nichrome luzisa ukusebenza okuthembekileyo, ukusebenza kakuhle kwamandla, kunye nokuqina okunzima ukuphindaphinda ezinye iindlela.
Ukukhetha ucingo oluchanekileyo kuthetha ukubeka phambili umxube oyingqayizivele wezakhiwo ezibonelela nge-nichrome kuphela. Iimveliso zethu zenziwe ukuba zihlangabezane nemigangatho engqongqo yomgangatho, ziqinisekisa ukuba zidlula izinto ezibambeleyo kuzo zombini ukusebenza kunye nokuphila ixesha elide-uzenza ukhetho oluhlakaniphile kwiimfuno zakho zokufudumeza.
