Quick answers

Aluminium or aluminum?

Same metal. IUPAC aluminium; US spelling aluminum. Specs use either.

Why is it light but not “weak”?

Specific strength of 7075 can beat mild steel; stiffness per volume still loses to steel.

Does it burn?

Bulk metal melts in fire; powders and some façade cores are the combustible stories.

Is it a good insulator?

No. It is a heat spreader. Foil radiant barriers reflect radiation; they are not bulk λ insulation.

Why do cans recycle so well?

Single alloy family, magnetic-free sort, huge volume, remelt energy is low.

Can I weld 7075?

Generally a bad idea for strength; designers rivet, bond or use 2000/5000 weldables instead.

Start with this section - Uses & pairings

Aluminium earns its keep in systems: a beam, a batt, a fibre blend, a coated steel — rarely a lone coupon.

Products below are cultural landmarks as much as SKUs.

Sectors

Aerospace

Skins, spars, seat tracks — still the volume airframe metal.

Packaging

Cans and foil: the recycling poster child.

Architecture

Curtain wall, roofing, composite panels (watch the core).

Transport

Rail cars, EV battery boxes, truck bodies.

Electrical

Busbars and overhead conductors.

Consumer

Laptops, cookware, heat sinks.

Pairings

CFRP

Hybrid airframes: aluminium where toughness and cost win, carbon where mass wins.

Steel fasteners

Isolate or coat — galvanic is not theoretical at the seacoast.

Polymer foam cores

ACP fire class is about the core, not the aluminium skins.

Anodic paint

Coil coatings for coastal roofs.

If the pairing is wrong, the material will be blamed for a system fault.
