Spectacular formability improvement of High Strength 7xxx alloys Cold Stamping of parts with a complex shape is not possible with classic 7xxx alloys in T4, T6 and T7x tempers. Such parts can, however, be stamped successfully by bringing the material into the fresh W-temper condition, prior to the cold stamping. W-temper is the condition of [...]

Special alloys for special processes AMAG TopForm® SPF is a serial production material that has been optimized for the superplastic forming process and offers unrivalled forming speed at temperatures within the 450-500°C range. This means that considerably more complex geometries can be achieved than are possible with conventional forming. This is an AlMgMn alloy, which [...]

L’effet de la température sur l’aptitude à la mise en forme des tôles en aluminium dans la gamme de 200 - 300 °C a été étudié par plusieurs métallurgistes depuis plusieurs décennies. Ils ont constaté une augmentation spectaculaire de la ductilité, particulièrement sur les alliages aluminium – magnésium de la famille 5000, associée à une [...]

Warm forming of aluminium parts: A way to bridge the gap between aluminium and steel The effects of temperature on the formability of aluminium sheets in the range of 200-300°C were studied by a number of workers some decades ago, who reported impressive ductility increase, especially on 5xxx alloys, associated with a decrease in work [...]
