The effect of modification with silicon carbide on the density of the secondary aluminum alloy of the Al-Si system

The effect of modification on the density of the secondary aluminum casting alloy (wt.%: 0, 528 Mg, 1, 124 Cu, 11, 539 Si, 84, 969 Al, 0, 905 Fe, 0, 692 Zn, 0, 242 Mn) was determined with the introduction of silicon carbide powder with a particle size of 1-3 μm in an amount of 0, 1, 0, 2, 0, 3 wt. %. It has been established that the density of the alloy of castings with a silicon carbide content of 0, 1 % is 2 761 kg/m3, and that of the unmodified alloy is 2 715 kg/m3. With an increase in the silicon carbide content to 0, 2%, the density of the metal is 2 735 kg/m3. With a SiC content of 0, 3 wt.%, the density of the alloy is 2 752 kg/m3. The density of the metal of the castings obtained in the sandy-clay form with the modifi cation of 0, 1% SiC is 2 673 kg/m3, with 0, 3% SiC - 2 676 kg/m3.
