Nichrome, yotchedwanso nickel chrome, ndi aloyi wopangidwa ndikusakaniza faifi tambala, chromium ndipo, nthawi zina, chitsulo. Chodziwika bwino kwambiri chifukwa chotsutsana ndi kutentha kwake, komanso kukana kwake kuzizira komanso makutidwe ndi okosijeni, aloyi ndi othandiza kwambiri pazinthu zingapo. Kuchokera pakupanga mafakitale kupita kuntchito zokonda kuchita zinthu, nichrome mu mawonekedwe amtundu wa waya imapezeka pamalonda osiyanasiyana, zaluso ndi zida. Ikupezanso ntchito m'malo apadera.

Waya wa Nichrome ndi aloyi wopangidwa ndi faifi tambala ndi chromium. Imakana kutentha ndi makutidwe ndi okosijeni ndipo imakhala ngati chowotcha muzinthu monga toasters ndi zowumitsa tsitsi. Othandizira amagwiritsa ntchito waya wa nichrome pazosema za ceramic ndikupanga magalasi. Waya imapezekanso muma laboratories, zomangamanga ndi zamagetsi apadera.

Chifukwa waya wa nichrome ndiwosagwirizana ndi magetsi, ndiwothandiza modabwitsa ngati chinthu chotenthetsera malonda ndi zida zapanyumba. Zoyeserera ndi zowumitsa tsitsi zimagwiritsa ntchito ma waya a nichrome kuti apange kutentha kwakukulu, monganso ma uvuni oyeserera ndi zotentha zosungira. Zitsulo zamagetsi zimagwiritsanso ntchito waya wa nichrome kuti zigwire ntchito. Kutalika kwa waya wa nichrome kungagwiritsidwenso ntchito kupangira chodulira waya chotentha, chomwe chitha kugwiritsidwa ntchito kunyumba kapena m'malo opanga mafakitale kudula ndikupanga thovu ndi mapulasitiki ena.

Waya wa Nichrome amapangidwa ndi non-maginito alloy opangidwa makamaka ndi faifi tambala, chromium, ndi chitsulo. Nichrome imadziwika ndi kutetezedwa kwake kwakukulu komanso kukana bwino kwa makutidwe ndi okosijeni. Nichrome waya imakhalanso ndi ductility yabwino itagwiritsidwa ntchito komanso kuwotcherera kwabwino kwambiri.

Chiwerengero chomwe chimabwera pambuyo pa mtundu wa waya wa Nichrome chikuwonetsa kuchuluka kwa faifi tambala mu aloyi. Mwachitsanzo, "Nichrome 60" ili ndi Nickel pafupifupi 60% momwe imapangidwira.

Kufunsira kwa waya wa Nichrome kumaphatikizanso zotenthetsera zowuma tsitsi, zotenthetsera kutentha, ndi chithandizo cha ceramic m'makina.
