Development of aluminium alloys for aerosol cans

New aluminium alloys were developed for aluminium narrow strips, cast with a rotary strip caster, to produce slugs for aerosol cans. The newly developed alloys provide constant mechanical properties during the manufacturing of aerosol cans, a good transformation and high deformable and burst pressures of the aerosol cans. The problem that occurs during the manufacturing of aerosol cans is a decrease in the mechanical properties of the material up to 15 %. This is reflected in lower deformable and burst pressures for the aerosol cans. By increasing the mechanical properties of aerosol-can materials it is possible to produce aerosol cans with thinner walls, having a significant impact on the weight of the final aerosol cans. Using new aluminium alloys for aerosol cans, it is possible to increase the deformability and burst pressure by more than 10 %.
