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 %.Keywords:
