  • Method of making an AA7000 series aluminum wrought product having a modified solution heat treating process for improved exfoliation corrosion resistance
    Patent number: 5785777
    Abstract: A method of producing an AA7000 series aluminum alloy wrought product or plate includes a two step solution heat treating sequence wherein the aluminum plate is subjected to a first solution heat treatment at a first elevated temperature or temperatures for a first period of time, followed by a second solution heat treatment at a lower temperature or temperatures for a second period of time. The two step solution heat treating sequence results in vastly improved exfoliation corrosion resistance in the final aluminum wrought or plate product. An improved process for making aluminum alloy products in the T7751 Temper also is disclosed.
