Guided journey / 4 stops / about 9 minutes

One metal, very different lives

The same element can become a foil, a frame or a heat-spreading core. Alloying, shape and processing change what it can do. This journey follows those changes without assuming that every product uses the same alloy.

Meet the starting material family

Low density, formability and conductivity help explain aluminium’s reach. The initial route from ore through alumina to metal is quite different from remelting collected scrap. Neither route identifies the source of a particular can.

Make a very thin shell

Drawing and ironing turn sheet into a thin container. The lid and body need not use the same alloy, and internal coatings perform another task. A familiar silver surface conceals an engineered package.

Make a load-bearing structure

A frame uses tubes and joints to resist loads while limiting mass. The geometry changes with material choice; simply replacing a steel tube with an equally sized aluminium tube is not a complete design.

STOP 4 / comparisons

Make a barrier only micrometres thick

In some cartons, aluminium becomes a thin barrier supported by other layers. This is very different from a can in both performance and recovery. The whole package determines the end-of-life route.

Material identity is the beginning of an explanation. Shape, alloy and interfaces finish it.
