CHAPTER 6 Applications for Aluminum Alloys and Tempers THERE ARE AT LEAST two approaches to overviewing important applications of aluminum alloys: by alloy class, as initiated in Chapter 3 and carried out in greater detail subsequently, and by type of application. Both approaches are considered in this chaptera review first by alloy class and then by application. Readers are referred to Aluminum: Technology, Applications and Environment (see Chapter 8) for more detailed information on many of the applications mentioned in this chapter. All photographs are courtesy of the Aluminum Association unless otherwise indicated, many from the reference noted in the previous paragraph. Applications by Alloy Class Wrought Alloys 1xxx, Pure Aluminum. The major characteristics of the 1xxx series are: O Strain hardenable O Exceptionally high formability, corrosion resistance, and electrical conductivity O Typical ultimate tensile strength range: 70 to 185 MPa (10–27 ksi) O Readily joined by welding, brazing, and soldering The 1xxx series represents the commercially pure (CP) aluminum, ranging from the baseline 1100 (99.00% min Al) to relatively purer 1050/1350
