Nichrome, oo sidoo kale loo yaqaano nikkel chrome, waa daawaha ay soo saarto isku dhafka nikkel, chromium iyo, marmar, birta. Sida ugu fiican ee loo yaqaan caabbinta kulaylka, iyo sidoo kale iska caabinta daxalka iyo oksaydhka labadaba, daawaha ayaa si cajiib ah faa'iido u leh tiro codsiyo ah. Laga soo bilaabo wax soo saarka warshadaha ilaa shaqada hiwaayadda, nichrome qaab silig ah ayaa ku jira noocyo kala duwan oo badeecado ganacsi ah, farshaxanno iyo qalabyo. Waxa kale oo ay ka heshaa codsiyada goobaha gaarka ah.
Siliga Nichrome waa daawaha laga sameeyay nikkel iyo chromium. Waxay ka hortagtaa kulaylka iyo oksaydhaynta waxayna u adeegtaa sidii walxaha kuleyliyaha ee alaabada sida toasters-ka iyo timaha qalajiyaha. Hiwaayadaha waxay isticmaalaan silig nichrome ah farshaxanimada dhoobada iyo samaynta dhalooyinka. Siligga waxa kale oo laga heli karaa shaybaadhada, dhismaha iyo qalabka elegtarooniga ah ee gaarka ah.
Sababtoo ah siligga nichrome aad ayuu ugu adkaysanayaa korontada, si cajiib ah ayay faa'iido u leedahay sida walxaha kuleyliyaha ee alaabta ganacsiga iyo qalabka guriga. Toasters iyo timo engejiya waxay isticmaalaan gariiradaha nichrome silig si ay u abuuraan xaddi badan oo kulayl, sida ay sameeyaan foornooyinka toaster iyo kuleyliyaha kaydinta. Foornooyinka warshadaha sidoo kale waxay isticmaalaan siligga nichrome si ay u shaqeeyaan. Dhererka siligga nichrome ayaa sidoo kale loo isticmaali karaa in lagu abuuro xargaha kulul, kaas oo loo isticmaali karo guriga ama goobta warshadaha si loo gooyo loona qaabeeyo xumbo iyo balaastikada qaarkood.
Siligga Nichrome wuxuu ka samaysan yahay daawaha aan magnetka ahayn oo ka kooban ugu horrayn nikkel, chromium, iyo iron. Nichrome waxaa lagu gartaa caabbinta sare iyo iska caabbinta oksaydhka wanaagsan. Siliga Nichrome sidoo kale wuxuu leeyahay ductility ka dib isticmaalka iyo alxanka wanaagsan.
Nambarka ka dambeeya nooca siliga Nichrome wuxuu muujinayaa boqolleyda nikkel ee daawaha. Tusaale ahaan, "Nichrome 60" waxa uu ka kooban yahay ku dhawaad 60% nikkel.
Codsiyada siliga Nichrome waxaa ka mid ah walxaha kululaynta timaha qalajiyaha, kulaylka daboolayaasha, iyo taageerada dhoobada ee kilns.
