Where Aluminium Goes: Transport Leads, Packaging Recycles Best
Transport takes the largest share of aluminium demand, but packaging, mostly cans, has the best-established recycling loop of any end use.
Transport
Vehicle bodies, aircraft structures, and rail, using the strength-to-weight advantage covered on the mechanics page.
Construction
Window frames, cladding, and structural extrusions, using the 6xxx alloy family covered on the materials science page.
Packaging
Cans and foil, the end use with the most mature, highest-volume recycling loop of any aluminium product.
Electrical
Overhead power lines, where aluminium's lower weight outweighs copper's higher conductivity per cross-section.
Machinery
Industrial equipment components across manufacturing sectors.
The breakdown
Transport leads because of the strength-to-weight economics covered on this material’s mechanics page, every kilogram saved on a vehicle or aircraft has a real, compounding fuel or energy cost over its service life. Packaging is the smaller category by tonnage but the one with by far the best-closed recycling loop: a large share of aluminium cans are recycled and back on shelves within roughly 60 days, and recycling consumes only about 5% of the energy primary smelting does, covered on this material’s supply chain page.
