Magnesium Die Cast Alloys for Elevated Temperature Applications 900788

Mechanical testing and prototyping of several developmental magnesium die cast alloys have shown that certain magnesium alloys can be exposed to temperatures in excess of 232°C (450°F) and still have adequate strength. For example, one of the alloys tested at 260°C (500°F) had a tensile yield strength greater than 87 HPa (12.7 ksi). Further testing also revealed that some of these alloys possess better creep strength at 316°C (600°F) than AZ91D has at 177°C (350°F) with at least as good castability as AS41A.
