Non-Ferrous Metal Rolling

This class covers the hot and cold rolling of non-ferrous metals to produce plates, sheets, strips, and foils, such as those from copper, aluminum, silver, zinc, magnesium, tin, and platinum. It also includes drawing, tempering, and stressing to manufacture metal wire—either single or stranded—whether for electrical conduction or not. Pipe and pipe fitting manufacturing from non-ferrous metals is excluded (see class 24205).
