A recently developed solid-state joining technique, namely friction stir welding (FSW), has been well demonstrated to produce joints with better joint performances in Al alloys, particularly in difficult-to-weld grades, than those obtained in more conventional fusion welding processes. The technique has already been implemented with joining Al alloys in various production lines such as shipbuilding, automobile, high-speed train manufacturing, and aviation industries. In this study, the applicability of friction stir welding to 63% Cu-37% Zn brass plate has been investigated. The joint performance values were determined by conducting optical microscopy, microhardness measurements, and mechanical testing (e.g., tensile and bend tests). The effects of the tool rotational speed (i.e., 1250 and 1600 rev/min) and the welding speed on the joint performance were determined. The best joint performances were obtained at a rotational speed of 1600 rev/min with a welding speed of 225 mm/min.
