Hai-Nicr70 Flat Wire for Double Strip Coils Braking Resistor
Hai-Nicr70 Flat WirenokutiKaviri Strip Coils Braking Resistor
Ni70Cr30is nickel-chromium alloy (NiCr alloy) inoratidzwa nepamusoro resistivity, yakanaka oxidation kuramba uye yakanaka kwazvo kugadzikana kwefomu. Inokodzera kushandiswa patembiricha inosvika 1250 ° C, uye inobata hupenyu hwesevhisi hwepamusoro kana ichienzaniswa neIron chromium alumium alloys.
Yakajairika maapplication eNi70Cr30zvinhu zvemagetsi zvekudziisa mumidziyo yemumba, mabindu emaindasitiri uye zvinopikisa (wayawound resistors, simbi firimu resistors), simbi dzakapfava, michina yekuayina, hita dzemvura, kuumbwa kwepurasitiki kunofa, simbi dzekutengesa, simbi sheathed tubular zvinhu uye cartridge zvinhu.
