Cuprul cu Al nu se "pupa", Cu "haleste" Al, nu se oxideaza, se transforma in sare.

Pe vremuri, avea matusa mea, o antena TV, din Al, la Slanic PH. Dupa un timp TV-ul mergea f nasol. Am verificat totul si am ajuns la antena. Locul unde firele de Cu ale coaxialului atingeau dipolul din Al, era mancat asa de tare, incat a trebuit sa pun suruburi ceva mai mari si cu saibe.

Firele de Cu "inotau" intr-o mare de sare, fina, alba si nu mai faceau contact cu dipolul.

Verifica si tu jonctiunile Cu-Al.
