This is the most versatile of the heat treatable aluminum alloys. It has most of the good qualities of aluminum, and it offers a wide range of mechanical properties and corrosion resistance. It can be fabricated by many of the commonly used techniques.

In the annealed condition it has good formability. In the T4 condition fairly severe forming operations may be accomplished. The T6 properties may be obtained by artificial aging.

It is welded by all methods and can be furnace brazed. It is available in the clad form ("Alclad") with a thin surface layer of high purity aluminum to improve both appearance and corrosion resistance.
