General
The lightweighting challenges imposed by changes in the policies of the regulatory agencies require the development of high strength materials that also offer weight saving. Aluminum has attracted the attention, especially in the automotive and aviation sector for its great weight savings when compared to steels while also providing corrosion resistance. The materials for current interest in the CMRG group are 5xxx, 6xxx and 7xxx alloys that can caterer to a wide range of applications.
