Ụlọ ọrụ Nichrome Alloy Strip nkeNi80Cr20Eji Ni70Cr30 Ni60Cr15 Ni35Cr20 na ngwa ụlọ
Ni70Cr30 bụ austenitic nickel-chromium alloy dabara maka ngwa okpomọkụ ruo 1250°C. Ọdịnaya chromium dị elu (30% na nkezi) na-enye ezigbo oge ndụ, ọkachasị na ngwa ọkụ. Ni70Cr30 e ji elu resistivity, ezi ọxịdashọn na-eguzogide, ezi ductility mgbe ojiji na magburu onwe weldability.
A na-eji Ni70Cr30 mee ihe maka ọkụ ọkụ eletrik na ọkụ ụlọ ọrụ. Ngwa ndị a na-ahụkarị bụ: ọkụ eletrik na ọkụ enamelling, igwe nchekwa nchekwa, ọkụ na kiln nwere ikuku na-agbanwe agbanwe.
