The aluminum chapter describes primary aluminum production and secondary processing with a strong focus on secondary processing. Secondary processing includes Recycling and Melting, Casting, Hot Working, Heat Treating, and Finish Coating. Mining and primary processing are presented, but not discussed in detail.

The above topics span a number of Standard Industrial Classification (SIC) codes:

3334 - Aluminum Production, Primary
3341 - Nonferrous Metals Smelting & Refining, Secondary
3353 - Aluminum Sheet, Plate, & Foil
3354 - Aluminum Extruded Products
3355 - Aluminum Rolling & Drawing
3363 - Aluminum Die Casting
3365 - Foundries, Aluminum
3398 - Heat Treating, Metal
3463 - Forging, nonferrous
