Ni70Cr30ndi 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 1250 ° C, ndipo imakhala ndi moyo wapamwamba wa utumiki poyerekeza ndi ma aloyi a Iron chromium aluminium.
Ntchito zofananira zaNi70Cr30ndi 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 zitsulo ndi zinthu za cartridge.
