I-alloy ye-nickel yethusi, enokumelana okuphansi kukagesi, imelana nokushisa nokugqwala okuhle, kulula ukuyicubungula futhi ihlanganiswe nge-lead. Isetshenziselwa ukwenza izingxenye ezibalulekile ku-relay yokushisa ngokweqile, i-thermal circuit breaker ephansi ukumelana, kanye nezinto zikagesi. Futhi iyinto ebalulekile yekhebula lokushisa likagesi. Ifana ne-s type cupronickel. Uma i-Nickel ihlanganiswa kakhulu, kulapho ubuso bumhlophe khona ngesiliva.
