Deep drawing, which is one of the pressing processes, is a processing method suitable for mass production because there are few manufacturing processes. Therefore, it is used in industrial products such as motor cases and fuel tanks, and daily necessities such as aluminum beverage cans and cooking pots. In recent years, there has been a demand for improved functionality of the cup itself in products made by deep drawing. The development of new processing methods and the establishment of processing using alternative materials are progressing. On the other hand, titanium, which is a kind of light metal, is expected as a next-generation material because it has excellent properties. Pure titanium is relatively ductile at room temperature and has excellent corrosion resistance, so it is used in heat exchangers and chemical plant components that come into contact with corrosion media. In the present study, to make a lightweight and functional cup, we tried to form the titanium clad cup with voids like the cross section of corrugated paper. The unique die with a steel ball attached to the shoulder of the die was combined with a normal die for deep drawing. The formability of the clad cup and the adhesiveness of the clad cup were investigated. By properly adopting the gap between the die and the blank with respect to the thickness of the blank sheet, it was possible to form the titanium paperboard cups with excellent stretchability.
