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 to a part or component. In this study, the mechanical properties and adhesion of a STS-Al-Mg, STS-Al, STS-Ti clad sheet are investigated. Blanking tests of the each material and clad sheet were performed at each direction and can be used to measure the bonding strength of clad sheet.
