The E-357 Aluminum Statistical Properties Project has received funding as part of the CIR program. The E-357 project will produce cast A&B design property allowables for this aluminum alloy for inclusion in the MMPDS (old Mil Spec Handbook 5) to meet FAA requirements. This will allow aerospace design engineers to specify castings without using design safety factors. The project is still in its infancy, but working groups are actively looking at melt practices, test casting gating and filling, heat treatment parameters, testing protocol, and weld repair standards. AFS VP Technical Services Tom Prucha gave a project overview of activities at the MMPDS meeting in May 2007 and is scheduled for an update at next meeting in October 2007.
