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