As part of a program of development of improved armoring components for body armor assemblies, samples of a magnesium alloy, Dowmetal Type J-1, have recently been tested at this laboratory. The resistance of these samples of perforation by cal. .45 steel-jacketed ball projectiles and by cal. .22 fragment-simulating projectiles, G-21, as normal incidence, was spectacularly lower than that of an equivalent weight of Hadfield manganese steel.
