Per NCCI's Scopes Code Description:

Parts may be anodized and some may have a Teflon-type coating. The finishing operations involve trimming, buffing, polishing, degreasing, etching, assembling and packing.

The operations include the cutting of aluminum ingots and billets to size, treating in an electric or gas fired furnace, the feeding to hydraulic extrusion presses to force the metal through dies to form the extrusions, stretching, straightening, cutting, polishing, drilling, wrapping and packing.
