The Clad sheet is made roll-bonding process of the one or more material with the different property. Good formability is an essential property in order to deform a clad metal sheet into a part or component. The performance of the clad sheet be considerably dependent at interfacial adhesion strength of between dissimilar materials because needs more research. In this study, were investigated the experiment variables when measured of interfacial bonding strength of STS/Al clad sheet by using the blanking process. Experimental variables are punch velocity, clearance and stacking sequence of the specimen. Also, were compared and analyzed with bonding strength as measured by T-peel test of standard peel test method. In addition, were compared at test results and FEM results by the blanking process by using the Sticking conditions of finite element analysis.
