Factory Nichrome Alloy Strip yeNi80Cr20Ni70Cr30 Ni60Cr15 Ni35Cr20 Inoshandiswa Mumidziyo Yemba
Ni70Cr30 is an austenitic nickel-chromium alloy yakakodzera kushandiswa kwetembiricha inosvika 1250°C. Yakakwira chromium yemukati (30% paavhareji) inopa hupenyu hwakanaka kwazvo, kunyanya mumashandisirwo echoto. Ni70Cr30 inoratidzirwa nepamusoro resistivity, yakanaka oxidation kuramba, yakanaka ductility mushure mekushandisa uye yakanakisa weldability.
Ni70Cr30 inoshandiswa kumagetsi ekudziya zvinhu muchoto cheindasitiri. Mashandisirwo akajairika ndeaya: mavira emagetsi uye enamelling, maheater ekuchengetera, mavira uye kilns ane shanduko yemhepo.
