Hereditary influence of the structure of charge materials on the density of aluminum alloys of the Al-Si system

The influence of dispersity of charge silicon and structure of initial charge alloys on the density of silumins of the Al-Si system is investigated using the improved express-method for determining the melt density. It is established that the structure of charge materials substantially and stably affects this characteristic, which should be taken into account in preparation technologies of alloys of the Al-Si system.
