摘要: Aluminum-strontium enriched master alloy granules for use primarily in modifying the eutectic phase in aluminum-silicon casting alloys. The master alloy granules are predominantly intermetallic compounds Al.sub.4 Sr, Al.sub.2 Sr or AlSr and mixtures thereof. By using such intermetallic dominant alloys in a granulated state rapid dissolution in aluminum-silicon alloy melts is achieved. The master alloy composition can be directly added to a content of the melt or injected into it. The master alloy composition can also be mixed with aluminum granules and extruded into a rod or entrained into a billet of cast aluminum.
