3004 Aluminium Foil

3004 aluminium foil is a manganese-bearing alloy that sits between the soft 1xxx series and the high-strength 5xxx series. It offers a practical balance of formability, strength and corrosion resistance, which is why it is often selected for parts that must hold their shape without giving up workability.

What is 3004 aluminium foil used for?

The alloy is commonly used for rigid and semi-rigid containers, lighting reflectors and housings, heat-exchange components, and a wide range of general industrial fabricated parts. Its moderate strength helps parts resist denting in handling and service, while its corrosion behaviour suits indoor and sheltered outdoor applications.

Which tempers are available?

Typical supply includes O (annealed), H14, H16, H18 and H22 tempers. Softer tempers favour deep forming and bending, while harder tempers provide greater stiffness for flat or lightly formed components. Temper selection should follow the amount of forming the part will receive and the stiffness the finished part needs.

What thickness range?

Standard production covers roughly 0.006 mm to 0.2 mm, with the exact availability depending on temper and width. Thin gauges suit flexible packaging and light container walls, while heavier gauges are used where more rigidity is required.

How is it packed?

Coils and rolls are normally supplied on cores, wrapped for moisture and dust protection, and secured on pallets or in wooden cases for transport. Packaging can be adapted for manual handling, automated unwinding lines or long-distance shipment.

Can width be customized?

Yes. Slitting width can be produced to suit the customer's forming equipment and finished part dimensions, within the limits of the selected thickness and temper. Sharing the target width, inner core diameter and roll weight helps confirm a suitable specification before ordering.
