Light, strong, ready for heat - Constellium’s Aeral sheet in modern cans

With Constellium’s Aeral aerosol can sheet, the humble deodorant can suddenly becomes an object of engineering - thin walls, high pressure, a familiar metal click in the hand, yet less material and better recyclability than the steel cans many consumers grew up with.

What Aeral actually is

Aeral is a specially developed aluminium alloy and sheet product that Constellium designed for monobloc aerosol cans in personal care and household products. The sheet is tailored to be drawn and wall-ironed into thin, seamless bodies that still withstand the internal pressures of aerosol formulations.

In practice that means: a roll of Aeral enters a can maker’s press line, and out come light, shiny cans ready for printing and filling. The aluminium structure has to survive multiple forming stages, baking of external coatings, and later the thermal cycles in transport and bathrooms.

Lighter cans, same tough safety

Constellium highlights that Aeral can enable up to around 30 percent weight reduction versus traditional steel aerosol cans, depending on the application and design. Less metal means less raw material, lower logistics emissions, and often a more comfortable feel in the hand because the can is not as top-heavy when half empty.

The safety bar stays high despite the slimming diet. Monobloc aluminium cans are expected to comply with strict pressure-resistance standards set by industry bodies and regulations, with burst pressures significantly above normal operating levels. Aeral is engineered so that thinning the wall does not compromise those thresholds.

Recycling and sustainability angle

Aluminium is prized for being endlessly recyclable without meaningful loss of quality, and Aeral leans into that narrative. Once emptied and properly sorted, cans made from this sheet can be melted and turned back into rolled products or other aluminium parts with relatively low energy input compared to primary production.

For brands, that recyclability story dovetails with lightweighting to support quantified carbon-footprint reductions for packaging portfolios. Combined with high-quality print surfaces and brand-friendly shapes, Aeral gives marketing teams something tangible to put into sustainability reports without sacrificing shelf impact.

How it changes can design

Because Aeral is optimised for deep drawing, designers can play more with elegant shoulders, slimmer waists, or taller silhouettes while keeping the strength envelope intact. You can feel that on the shelf: aluminium aerosol cans often have crisp curves and clean seams compared with older three-piece steel bodies.

The sheet’s surface finish also supports detailed lithography and glossy or matte coatings. That helps premium deodorant and hair-care brands differentiate themselves within the tight vertical space allotted in many supermarket and drugstore aisles.

Production realities for fillers

Aeral is designed to be compatible with existing high-speed can-making equipment, which matters for fillers running millions of units per year. Line operators should not need exotic tooling, just process parameters tuned to the specific alloy and gauge.

For aerosol fillers further down the chain, aluminium cans made from Aeral work with established valve crimping and gassing processes. The main operational differences show up in pallet weights and transport costs rather than in the filling hall itself, which keeps changeover risk manageable for large customers.

Where customers will encounter it

End consumers rarely see the word Aeral on a label, but they encounter it every morning in the bathroom mirror. Several global personal-care and household brands use aluminium aerosol cans supplied by Constellium’s can maker customers, especially in Europe and North America.

From antiperspirants to hairsprays and air fresheners, the visual cue is that seamless aluminium cylinder with a crisp shoulder and a glossy printed body. In many ranges, the lighter feel and lack of visible side seams quietly signal the shift away from older steel containers.

Competitive landscape and limits

Aeral is not alone. Steel aerosol cans and other aluminium alloys still dominate many price-sensitive segments, particularly in emerging markets where raw-material and conversion costs weigh heavily. For some aggressive formulations, pack owners may still prefer thicker walls or alternative materials.

There is also a packaging debate around aerosols in general, given propellant use and recycling-system challenges when cans are not fully emptied. Aeral can improve material efficiency and recyclability, but it does not solve every environmental and regulatory question around aerosol delivery systems.

Company context and listing

Constellium SE positions Aeral within its broader Packaging and Automotive Rolled Products segment, alongside can sheet for beverages and other speciality alloys. The product helps the group lock in high-value packaging customers in a market that historically leans on long-term contracts.
