The Metallographic Structure and Mechanical Properties of the Brazing Weld of 3003 Aluminum Alloy

Abstract:

The microstructure and properties of brazing weld of 3003 Aluminum Alloy has been studied by using the methods of microstructure observation(SEM), and mechanical-ability was tested. The results showed that the tensile strength reaches 146.2MPa which is close to that of the parent metal. The metallographic structure is α(Al) and α(Al)+Si eutectic structure. The metallographic structure affect the tensile strength and rigidity of the weld joint.
