MECHANICAL-PROPERTY DATA HM21A MAGNESIUM

Abstract

This alloy is one of a fairly recently developed series of heat- treatable magnesium alloys containing thorium and manganese as hardeners. It is intended primarily for service from 500 to about 800F, where it is superior from a strength standpoint to the other magnesium alloys available in sheet and plate form. This alloy can be welded and need not be stress relieved to prevent stress corrosion. It should be noted that HM21A in the -T81 temper is strain-rate sensitive. The nominal composition of HM21A is as follows: 2.0 thorium, 0.80 manganese, other impurities to total not more than 0.30.
