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 asebenza kanzima kanye nokumelana kwezimoto zikagesi. Izinhlobo ezahlukene zisetshenziselwa izintambo zokushisa ezinamazinga okushisa aphansi omqhubi kanye nokushiswa kwamashubhu "kuma-fittings okushiswa kagesi".Ingxubevange ye-Manganese yethusikusetshenziswa izinto ezijwayelekile zokumelana okunembile, okujwayelekile kanye nama-shunt.
