Ni80Cr20 Fiilo Fidsan oo Nikkel Chrome ah oo loogu talagalay Walxaha Kululaynta

Siligga fidsan ee Nichrome 8020, oo ka kooban 70% nikkel iyo 30% chromium, waa badeeco gaar ah oo dahaarka ah. Muuqaalkeeda fidsan wuxuu bixiyaa meel sare oo ballaaran, taasoo kor u qaadaysa hufnaanta kala-baxa kulaylka iyadoo la ilaalinayo iska caabin heer sare ah. Iyada oo ku faanaysa iska caabin koronto oo sare, waxay si fiican ugu habboon tahay kuleylinta qalabka warshadaha, foornooyinka, iyo codsiyada kale ee heerkulka sare. Iyada oo ay ugu wacan tahay iska caabinta oksaydhka adag iyo xoogga farsamada, siliggan fidsan wuxuu hubiyaa waxqabad joogto ah iyo cimri dheer oo adeeg ah, taasoo ka dhigaysa doorasho lagu kalsoonaan karo oo loogu talagalay mashaariicda ku salaysan kuleylinta iyo iska caabinta.
