Analysis of Organizations of Brazed Seam 5052 Al Alloy Contact Reactive Brazing

Abstract:

Test of 5052 Al alloy contact reactive brazing has been conducted in the case of special brazing parameters, using Cu foil-Mg power-Cu foil as reaction layer material, the microstructure were analyzed and discussed primarily. The results show that the brazing seam structure consisted of α-Al solid solution and CuAl₂ intermetallic compound; the organizations of brazed seam include Al (Mg, Cu) solid solution CuAl₂ binary intermetallic compound, complicated ternary intermetallic compound and Al₂MgO₄.
