    Abstract

    Cup height testing remains an important means of judging relative formability of aluminum alloys. This is true in both alloy development work and plant quality control. In this paper a comparison is given between Ball Punch Deformation Testing (Olsen cup) and a cupping test incorporating a 10.2-cm (4-in.)-diameter spherical punch. The merits and inadequacies of both tests in distinguishing differences in formability of aluminum alloys is discussed.
