Nichrome / Heat Element Resistance Waya / Flat Waya
Nichrome / Kutentha ElementResistance Waya/ Flat Waya
Ni80Cr20ndi nickel-chromium alloy (NiCr alloy) yodziwika ndi kukana kwambiri, kukana kwa okosijeni wabwino komanso kukhazikika kwa mawonekedwe abwino kwambiri.Ndi yoyenera kugwiritsidwa ntchito pa kutentha mpaka 1200 ° C, ndipo imakhala ndi moyo wapamwamba wa utumiki poyerekeza ndi ma aloyi a Iron chromium aluminium.
Ntchito zofananira zaNi80Cr20ndi zinthu zotenthetsera zamagetsi pazida zam'nyumba, ng'anjo zam'mafakitale ndi zopinga (zopinga mawaya, zotchingira mafilimu azitsulo), zitsulo zosalala, makina akusita, zotenthetsera madzi, kuumba pulasitiki kumafa, zitsulo zomangira, zitsulo zomata ndi zinthu za cartridge.
