Abstract: An apparatus and a method for sorting, particularly chopped, aluminum scrap by alloy groups are disclosed, in which the aluminum scrap is separated into fractions, fractions of the aluminum scrap are irradiated by at least one neutron source, the gamma radiation that the individual fraction emits due to this neutron irradiation is detected by at least one detector, and based on this, an energy spectrum associated with the respective fraction is generated, based on which energy spectrum a relative ratio of the weight proportions of at least two alloy elements of this fraction is determined, and based on this relative ratio, this fraction is allocated to its corresponding alloy group, and then the fractions are sorted by the alloy groups to which they have been allocated.

Abstract: A diecasting alloy based on Al—Si is made of 6 to 12% by weight of silicon (Si), at least 0.3% by weight of iron (Fe), at least 0.25% by weight of manganese (Mn), at least 0.1% by weight of copper (Cu), 0.24 to 0.8% by weight of magnesium (Mg) and 0.40 to 1.5% by weight of zinc (Zn). The alloy also has 50 to 300 ppm of strontium (Sr) and/or 20 to 250 ppm of sodium (Na) and/or 20 to 350 ppm of antimony (Sb), and at least one of the following constituents: titanium (Ti) to an extent of not more than 0.2% by weight; not more than 0.3% by weight of zirconium; not more than 0.3% by weight of vanadium (V); and as the remainder aluminium and unavoidable impurities resulting from the production. The total content of Fe and Mn in the diecasting alloy together is not more than 1.5% by weight, the quotient of the percentages by weight of Fe and Mn is 0.35 to 1.5, and the quotient of the percentages by weight of Cu and Mg is 0.2 to 0.8.
