Izinhlobo ezahlukene zama-alloy aphezulu e-Copper kanye ne-Nickel aqukethe ukumelana okuphezulu noma okuphansi okuqondile ziphawuleka ngokumelana okuphansi kokushisa. Njengoba zinokumelana okuphezulu kokugqwala kanye nokugqwala kwamakhemikhali, lawa ma-alloy asetshenziselwa ama-resistor aqondile e-wire-wound, ama-potentiometer, amadivayisi okulawula ivolumu, ama-rheostat ezimboni aqinile kanye nokumelana kwezimoto zikagesi. Izinhlobo ezahlukene zisetshenziselwa izintambo zokushisa ezinamazinga okushisa aphansi omqhubi kanye nokushiswa kwamashubhu “ku-fittings kagesi yokushiswa”. I-Copper Manganese alloy isetshenziswa njengezinto ezijwayelekile zama-resistor aqondile, ajwayelekile kanye nama-shunt.
