Advances in Aluminum Foundry Alloys for Permanent and Semi-Permanent Mold Casting

  • J. Major
  • M. Hartlieb


The permanent (PM) and semi-permanent (SPM) mold processes are commonly implemented for a wide range of aluminum applications. Examples include sophisticated aerospace and military parts, through common commercial castings, and on to high volume automotive applications like engine blocks, cylinder heads and suspension components. This paper describes some recent aluminum alloy developments aimed at expanding the markets available to the PM and SPM foundry industry. Topics covered include developments which address the castability of difficult alloys, alloy developments for high strength and/or high temperature applications, and opportunities for cost savings in the areas of heat treatment.
