  • Strontium-aluminum intermetallic alloy granules
    Patent number: 6210460
    Abstract: Compositions suitable for use as an inoculant for cast iron. The composition includes granules of intermetallic alloys selected from Al4Sr, Al2Sr, and AlSr. The composition consists essentially of 40 to 81 percent strontium by weight.
    Type: Grant
    Filed: December 18, 1998
    Date of Patent: April 3, 2001
    Assignee: Timminco Limited
    Inventors: Douglas J. Zuliani, Bahadir Kulunk
  • Strontium-aluminum intermetallic alloy granules
    Patent number: 6132530
    Abstract: 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.
