The present invention relates to absorbent articles which include a primary and a secondary element, whereby the element positioned towards the wearer has a higher ultimate storage capacity than the outer one, and further providing a superior skin dryness performance. The components have yield strengths of 82 to 100 KSI, tensile strengths of 88 to 106 KSI, 12 to 19% elongation’s, and 7 to 10% reduction areas, and a method for heat treating the scandium containing aluminum alloy. Further, a method for verifying a bus interface by creating a corner case situation is provided. The connector body and unit of the female type connector assembly are connected together through a contact.
