Aluminum alloys corrosion description

Aluminum alloys consist of several families, used for low density (lightness), corrosion resistance and high strength-to-weight ratio. Aluminum alloy descriptions comprise the alloy designation plus the thermal-mechanical condition (temper designation), such as 6061-T6. See Figure 4-13. 

Many materials experience several of the above forms of corrosion. Some forms of attack are more prevalent in certain materials, e.g., exfoliation is well known in aluminum alloys and selective leaching can occur in copper-zinc alloys. A more complete description of corrosion types is found elsewhere in this book and is discussed in the literature [i-3].
