Kwi-coils e-Galvamited, intsimbi yephepha intywiliselwa kwi-binc ye-zungu e-chinc ukwenza iphepha le-zinc lihlanganiswe kumphezulu wayo. Ubukhulu becala iveliswa yinkqubo eqhubekayo yokugalela, oko kukuthi, ipleyiti yentsimbi eqengqelekisiweyo intywiliselwa ngokuqhubekayo kwitanki yokucoca nge-zinc enyibilike ukwenza ipleyiti yentsimbi; ipleyiti yentsimbi edibeneyo. Olu hlobo lwepleyiti yentsimbi lukwaveliswa ngendlela yediphu eshushu, kodwa kwangoko emva kokuba iphumile etankini, ifudunyezwa malunga ne-500 ℃ ukuze yenze ingxubevange ye-zinc kunye nentsimbi.
