Pofufuza cholowa m'malowaya wa nichrome, m'pofunika kuganizira zapakatikati zomwe zimapangitsa kuti nichrome ikhale yofunika kwambiri: kukana kutentha kwambiri, kusasunthika kwamagetsi, kukana dzimbiri, komanso kulimba. Ngakhale zida zingapo zimayandikira, palibe chomwe chimagwirizana ndi magwiridwe antchito a nichrome - kupanga ma waya a nichrome kukhala odalirika pazogwiritsa ntchito zovuta.
Njira imodzi yodziwika bwino ndi kanthal wire, anchitsulo-chromium-aluminium aloyi. Kanthal amachita bwino kwambiri m'malo otentha kwambiri, kupirira kutentha mpaka 1,400 ° C, komwe ndikwapamwamba kuposa magiredi ena a nichrome. Komabe, ndi yolimba kwambiri komanso yosasunthika kwambiri, zomwe zimapangitsa kuti zikhale zovuta kuzipanga kukhala zojambula zovuta kwambiri. M'mapulogalamu omwe amafunikira kusinthasintha, monga zinthu zing'onozing'ono zotenthetsera zamagetsi, kanthal nthawi zambiri imakhala yochepa, pamene ductility ya nichrome imalola kupanga bwino popanda kusweka.
Waya wa Copper-nickel (Cu-Ni) ndi wotsutsana winanso, wamtengo wapatali chifukwa cha kukana kwake kwa dzimbiri komanso kupirira pang'ono. Koma Cu-Ni imalimbana ndi kutentha kwakukulu, kumatulutsa oxidizing mofulumira kuposa 300 ° C, zomwe zimalepheretsa kugwiritsidwa ntchito kwake muzochitika zotentha kwambiri monga ng'anjo za mafakitale kapena mawotchi otentha. Nichrome, mosiyana, imakhala yokhazikika ngakhale pa 1,200 ° C, ndikupangitsa kuti ikhale yosinthasintha kwambiri pa ntchito zotentha kwambiri.
Waya wa Tungsten amapereka kutentha kwapadera, kupirira kutentha kwambiri mpaka 3,422 ° C. Komabe, ndi yolimba kwambiri ndipo imakhala ndi mphamvu zochepa zamagetsi, zomwe zimafuna mafunde apamwamba kuti apange kutentha. Izi zimapangitsa kuti zikhale zosagwira ntchito zotenthetsera zambiri momwe mphamvu zogwiritsira ntchito mphamvu ndi zosavuta zogwiritsira ntchito - madera omwe nichrome, ndi mphamvu yake yabwino yolimbana ndi ntchito, imawala.
Waya wachitsulo chosapanga dzimbiri nthawi zambiri amaganiziridwa kuti angakwanitse komanso kukana dzimbiri. Komabe, imakhala ndi mphamvu yocheperako kuposa nichrome, kutanthauza kuti imapanga kutentha pang'ono pautali wa unit, zomwe zimafuna ma geji akuluakulu kapena ma voltages apamwamba kuti agwirizane ndi kutulutsa kwa nichrome. Pakapita nthawi, chitsulo chosapanga dzimbiri chimayambanso kupunduka chifukwa cha kutentha kwanthawi yayitali, kumachepetsa moyo wake poyerekeza ndi kukhazikika kwanthawi yayitali kwa nichrome.
Zogulitsa zathu zamawaya za nichrome zimathetsa malire awa m'malo. Amapezeka m'makalasi osiyanasiyana (mongaNiCr 80/20), amapereka resistivity yolondola ya kutentha kosasinthasintha, ductility yabwino kuti ikhale yosavuta, komanso kukana kwa okosijeni kwapamwamba pa kutentha kwakukulu. Kaya ndi zinthu zotenthetsera pazida zamagetsi, zida za labotale, kapena ng'anjo zamakampani, waya wathu wa nichrome amapereka magwiridwe antchito odalirika, kuwongolera mphamvu, komanso kulimba komwe njira zina zimavutikira kubwereza.
Kusankha waya wolondola kumatanthauza kuyika patsogolo kuphatikiza kwapadera kwa zinthu zomwe nichrome yokha imapereka. Zogulitsa zathu zidapangidwa kuti zikwaniritse miyezo yapamwamba kwambiri, kuwonetsetsa kuti zimaposa zolowa m'malo mwazochita zonse komanso moyo wautali - kuzipanga kukhala chisankho chanzeru pazosowa zanu zotenthetsera.
