In conjunction with a program of development of improved body armor components which is being conducted at this arsenal in response to a request of the Office, Chief of Ordnance, samples of four aluminum alloys have been tested in thin .125 in. sheet form. Of the four alloys tested R-301T, R301W, 14S-W, 24S-RT the resistance of the 24S-RT sample to perforation by caliber .45 steel jacketed ball projectiles and by a light-weight 17 grain fragment simulator was highest and that of the R-301T sample lowest. However, as compared with that of Hadfield manganese steel of equivalent weight the resistance of all these alloys was remarkably poor.
