1Cr13Al4 FeCrAl alloy Bright Flat Strip/Tsarin Fadi don Amfani da Resistors

Fecral Alloys da Nickel-chromium alloys an zaɓi su zama kayan juriya don abin da aka saka saboda nickel-chromium alloys suna da babban juriya na lantarki wanda ake amfani da shi sosai don masu tsayayyar fim na bakin ciki [1, 2]. Juriyar takarda na fim ɗin nickel-chrome gami da 20% chromium na iya zama sama da 2-3 kilo ohms kuma har yanzu yana kula da kwanciyar hankali. Matsakaicin zafin jiki na 1 na juriya (TCR) don ƙarami nickel-chrome gami yana kusan 110 ppm/°C. Ta hanyar haɗa ƙaramin siliki da aluminium tare da nickel-chromium, ana ƙara haɓaka kwanciyar hankali.
