초록

The clad sheet is the sheet metal that joined the one or more material with the different property by rolling process. In this study, it is investigated about the mechanical property or formability of SUS-Al-Mg clad sheet. The clad sheet was formed at elevated temperature because of their poor formability at room temperature. The tensile test was confirmed at various temperature and the reduction of strain rate above $250^{\circ}C$. LDR(Limited Drawing Ratio) was obtained through deep drawing test to confirm the formability of the clad sheet. The FE analysis is performed to compare prototype products.
