This chapter describes how aluminum sheet and foil alloys are processed to produce functional, economical packages that meet the various industry performance criteria. The focus is on the key customer requirements for three main application segments: foil, cans, and impact extrusions. A huge range of products in this industry segment is also illustrated. The need for sustainable production and recyclability is also discussed.

This chapter discusses the composition and structure of low-carbon irons and steels, particularly those used in the production of hot-rolled strip. It describes the manufacturing process from the production of ingots to coiling, and it explains how finishing and coiling temperatures affect ferritic grain size and the distribution of cementite particles. It also discusses subsequent processing, including cold rolling and annealing, and the parameters with the greatest impact on grain size and microstructure. In addition, it describes the production of enameling irons, the benefits of high-temperature heat treatments, and the effects of quench and strain aging.
