Results of presented of tests to determine the effect of brake forming in various tempers on the strength of Alclade 75S-T aluminum-alloy sheet in the direction parallel to the brake. The tensile and compressive strengths of Alclad 75S-T sheet, formed in the O and W tempers, were either increased or little affected as compared with those of similarly treated unformed material. When Alclad 75S-T sheet "as received" was formed, however, the tensile yield stress was reduced about 7 percent for the with-grain direction and 1 percent for the cross-grain direction, whereas the tensile ultimate and compressive yield strength stresses were increased somewhat. The elongation was always slightly reduced as a result of forming.
