Nicr 80/20 Nicr 60/15 Riboni / Flat Waya wa Braking Resistor
NiCr 80/20 NiCr 60/15 Riboni / waya wathyathyathya wa Braking Resistor
Ni80Cr20 ndi aloyi ya nickel-chromium (NiCr alloy) yodziwika ndi resistivity yapamwamba, 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 za Ni80Cr20 ndi zamagetsikutentha chinthus mu zida zapakhomo, ng'anjo zam'mafakitale ndi zopinga (zopinga mawaya, zotchingira mafilimu azitsulo), zitsulo zosalala, makina okusita, zotenthetsera madzi, kuumba pulasitiki kumafa, zitsulo zomangira, zitsulo zomata zitsulo ndi zinthu za cartridge.
