In the Al–Cu alloy the effect of a constant magnetic field in modes characterized by the Hartmann number 68 $\leq Ha \leq$ 679 on the redistribution of Cu and Fe in the joints of several grains and between two grains is established. The effect of the field on the change in the number and distribution of inclusions of intermetallic compounds formed in the intergrown volume is determined. As found, the magnetic field, in comparison with the alloy not exposed to it, increases the number of inclusions containing copper and decreases the number of inclusions containing iron in the alloy based on aluminium. Treatment of the alloy in the 68 $\leq Ha \leq$ 340 mode reduces the depth of intergranular corrosion. The hardness of the alloy increases at 68 $\leq Ha \leq$ 679. As established, the alloy structure formed under the condition $Ha$ = 68 provides the highest level of properties.
Key words: Al–Cu alloy, intergranular volume, intermetallics, hardness, corrosion, magnetic field.
