Abstract
A basic study has been made in order to obtain a brazing sheet having a high resistance to deformation during brazing. At first, the amount of deformation at brazing temperature of 610°C was measured on several brazingsheet specimens consisting of 4343 cladding alloy (both sides cladding) and Al-1.2%Mn base core alloys having no impurity or containing a small amount of Si, Fe, Cu, Mg, etc., as a function of cold reduction of specimens. Marked deformation was observed in the Si contained specimen (Si is added to the core alloy) cold-rolled by 515% and in the Fe contained specimen with a large reduction. Then, the two sorts of deformation were studied in detail in view of reaction at the interface between solid core and liquid phase of cladding alloy. It was found that the microstructure of core alloys at brazing temperature was of great importance for the stability of interface. It was concluded that in order to get an excellent brazing sheet, the core alloy was needed to show a completely recrystallized structure having coarse and elongated grains. The Al-Mn binary specimen free from impurity would satisfy the above condition.
