Nichrome / Kutentha ElementResistance Waya/ Flat Waya
Ni80Cr20ndi nickel-chromium alloy (NiCr alloy) yodziwika ndi kukana kwakukulu, 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 zodziwika bwino za Ni80Cr20 ndi zinthu zotenthetsera zamagetsi m'zida zam'nyumba, ng'anjo zam'mafakitale ndi zopinga (zopinga mawaya, zotchingira filimu zachitsulo), zitsulo zosalala, makina okusita, zotenthetsera madzi, pulasitiki ikafa, zitsulo zomangira, zitsulo zomata zitsulo ndi zinthu za cartridge.
