Abstract: A method of making a wrought aluminium-magnesium alloy rolled product, having a composition (in wt. %) of: 3.1<Mg<4.5; 0.4<Mn<0.85; 0.4<Zn<0.8; 0.06<Cu<0.35; 0.06<Cr<0.2; Fe<0.35; Si<0.2; Zr<0.05; Ti<0.3; impurities?0.05 each up to a total of max. 0.15, and balance aluminium.

Abstract: Process for the electrolysis of Al2S3, using a bath of molten salt, preferably a bath of molten chloride salt, in which Al2S3 is dissolved characterized in that measures are taken to improve the electrical conductivity of the bath, so as to enable an increase in the current density in the bath.

Abstract: A brazing product, e.g. a brazing sheet product, having an aluminium layer made of an aluminium alloy comprising silicon in an amount in the range of 2 to 18 weight %, and a layer comprising nickel on the outer surface of the aluminium layer such that taken together the aluminium layer and all layers exterior thereto form the filler metal for a brazing operation. The filler metal has a composition containing at least one element: (i) with a smaller exchange current density for the Hydrogen Evolution Reaction (“HER”) than nickel and/or (ii) such that the electro-chemical potential difference between particles of Ni-aluminide(s) of the filler and the aluminium alloy matrix of the filler is reduced. The filler metal's mol-ratio of Ni to such element(s) is in the range of 10:(0.3-30). The invention also relates to a method of manufacturing a brazed assembly using the brazing product, and to a brazed assembly comprising at least one component made of the brazing product.

Abstract: Disclosed is a method of manufacturing an aluminium or aluminium alloy joined product, such as a shaped and hollow member, comprising the sequential steps of: (a) providing two parts made of aluminium or aluminium alloy, each part having a peripheral flange; (b) positioning the two parts such that the peripheral flange of one part faces the peripheral flange of the other part to form an assembly, and joining the facing flanges of the two parts by heating.
