ABSTRACT:
Inconsistent and costly corrosion protection with prior art heat exchangers are eliminated in a heat exchanger (10) formed of an aluminum fin (16) clad with an Al--Si--Zn braze clad compound (18), an aluminum tube (14) brazed to the fin (16), and bonded thereto by the braze clad compound (18) with zinc diffused into the tube, whereby the aluminum tube (14) is corrosion resistant by reason of the presence of sacrificial zinc therein.
