Wrought heat treatable 7xxx alloys are more responsive to precipitation hardening than the 2xxx series alloys and can achieve higher strength levels, approaching tensile strengths of 690 MPa (100 ksi). This article provides an overview of key metallurgy, properties, and applications of the 7xxx aluminum alloy. It also illustrates the natural aging characteristics of 7050 aluminum sheet alloys at room temperature and relationships among commonly used alloys in the 7xxx series.
