  • Patent number: 10612115
    Abstract: The invention relates to a method for producing a strip made of an AlMgSi alloy in which a rolling ingot is cast of an AlMgSi alloy, the rolling ingot is subjected to homogenization, the rolling ingot which has been brought to rolling temperature is hot-rolled, and then is optionally cold-rolled to the final thickness thereof. The problem of providing a method for producing an aluminum strip made of an AlMgSi alloy and an aluminum strip, which has a higher breaking elongation with constant strength and therefore enables higher degrees of deformation in producing structured metal sheets, is solved in that the hot strip has a temperature of no more than 130° C. directly at the exit of the last rolling pass, preferably a temperature of no more than 100° C., and the hot strip is coiled at that or a lower temperature.

  • Patent number: 10113222
    Abstract: The invention relates to an aluminium alloy, the use of an aluminium alloy strip or sheet and a method for producing an aluminium alloy strip or sheet. An aluminium alloy which has only a slight tendency towards intercrystalline corrosion and which at the same time provides high levels of strength and good deformability and which contains standard alloy components so that the recycling of the aluminium alloy is simplified is provided herein.

  • Publication number: 20140190595
    Abstract: The invention relates to a method for producing a strip made of an AlMgSi alloy, in which a rolling ingot made of an AlMgSi alloy is cast, the rolling ingot is subjected to homogenization, the rolling ingot having been brought to rolling temperature is hot-rolled and is optionally cold-rolled to the final thickness thereafter. The problem of providing an improved method for producing aluminum strip made of an AlMgSi alloy, with which AlMgSi strips having very good shaping behaviour can be produced reliably, is solved in that immediately after exit from the final rolling pass, the hot strip has a temperature of between more than 130° C., preferably 135° C., and at most 250° C., preferably at most 230° C., and the hot strip is wound up at this temperature.
