Alumina Refining and Primary Aluminum Production

This includes establishments primarily engaged in one or more of the following: (1) refining alumina (i.e., aluminum oxide) generally from bauxite; (2) making aluminum from alumina; and/or (3) making aluminum from alumina and rolling, drawing, extruding, or casting the aluminum they make into primary forms. Establishments in this industry may make primary aluminum or aluminum-based alloys from alumina.

Secondary Smelting and Alloying of Aluminum

This includes establishments primarily engaged in (1) recovering aluminum and aluminum alloys from scrap and/or dross (i.e., secondary smelting) and making billet or ingot (except by rolling) and/or (2) manufacturing alloys, powder, paste, or flake from purchased aluminum.

Aluminum Sheet, Plate, and Foil Manufacturing

This includes establishments primarily engaged in (1) flat rolling or continuous casting sheet, plate, foil and welded tube from purchased aluminum and/or (2) recovering aluminum from scrap and flat rolling or continuous casting sheet, plate, foil, and welded tube in integrated mills.

Other Aluminum Rolling, Drawing, and Extruding

This includes establishments primarily engaged in (1) rolling, drawing, or extruding shapes (except flat rolled sheet, plate, foil, and welded tube) from purchased aluminum and/or (2) recovering aluminum from scrap and rolling, drawing, or extruding shapes (except flat rolled sheet, plate, foil, and welded tube) in integrated mills.

Illustrative Examples:

Aluminum bar made by extruding purchased aluminum
Nails, aluminum, made in wire drawing plants
Structural shapes made by rolling purchased aluminum
Rod made by extruding purchased aluminum
Tube made by drawing or extruding purchased aluminum
Wire, bare, made in aluminum wire drawing plants

Copper Rolling, Drawing, Extruding, and Alloying

Establishments in this category are primarly engaged in one or more of the following: (1) recovering copper or copper alloys from scraps; (2) alloying purchased copper; (3) rolling, drawing, or extruding shapes (e.g., bar, plate, sheet, strip, tube, wire) from purchased copper; and (4) recovering copper or copper alloys from scrap and rolling, drawing, or extruding shapes (e.g., bar, plate, sheet, strip, tube, wire).

Sign Manufacturing

Establishments in this category are primarly engaged in manufacturing signs and related displays of all materials (except printing paper and paperboard signs, notices, displays).

Engineering Services

Establishments in this category are primarly engaged in applying physical laws and principles of engineering in the design, development, and utilization of machines, materials, instruments, structures, processes, and systems. The assignments undertaken by these establishments may involve any of the following activities: provision of advice, preparation of feasibility studies, preparation of preliminary and final plans and designs, provision of technical services during the construction or installation phase, inspection and evaluation of engineering projects, and related services.

Illustrative Examples:

Civil engineering services
Environmental engineering services
Construction engineering services
Mechanical engineering services
Engineers' offices
Robotics automation engineering services

Research and Development in Nanotechnology

This includes establishments primarily engaged in conducting nanotechnology research and experimental development. Nanotechnology research and experimental development involves the study of matter at the nanoscale (i.e., a scale of about 1 to 100 nanometers). This research and development in nanotechnology may result in development of new nanotechnology processes or in prototypes of new or altered materials and/or products that may be reproduced, utilized, or implemented by various industries.

Research and Development in the Physical, Engineering, and Life Sciences (except Nanotechnology and Biotechnology)

This includes establishments primarily engaged in conducting research and experimental development (except nanotechnology and biotechnology research and experimental development) in the physical, engineering, and life sciences, such as agriculture, electronics, environmental, biology, botany, computers, chemistry, food, fisheries, forests, geology, health, mathematics, medicine, oceanography, pharmacy, physics, veterinary, and other allied subjects.
