Received 05.11.2019 UDK 669.715:621.745:538.4 The effect of a constant magnetic field in the range of numbers Ha = 0-170 on the structure and properties of cast aluminum alloy with copper and silicon of AK12M2 type is investigated. Using magnetic field treatment, both coarsening and grinding of the grains of the alloy are carried out, they are saturated with paramagnetic elements Ti, Sn and diamagnetic Cu and Zn, and the phase ratio in the cast structure is regulated. As a result, the hardness level of the alloy, slowly cooled in the alundum form under the influence of the field, corresponded to the heat-treated alloy crystallized under pressure. The level of copper saturation of the grains of the alloy obtained directly during crystallization in the field was close to the heat-treated metal. The corrosion resistance of the alloy increased without the use of special additives. The use of a constant magnetic field during crystallization of the alloy makes it possible to save alloying, modifying additives and electricity.
