MIL-DTL-32341A, DETAIL SPECIFICATION: ARMOR PLATE, ALUMINUM, ALLOY 2139 WELDABLE and ALLOY 2195 and 2060 UNWELDABLE APPLIQUE (15-APR-2015)

MIL-DTL-32341A, DETAIL SPECIFICATION: ARMOR PLATE, ALUMINUM, ALLOY 2139 WELDABLE and ALLOY 2195 and 2060 UNWELDABLE APPLIQUE (15-APR-2015)., This specification covers three wrought aluminum armor plate alloys for both welded and un-welded applications in nominal thicknesses from 0.500 to 4.000 inch, inclusive (see 6.2). An additional application for the AA2139 alloy with the T84 temper is also included in this specification for ballistic plate with an ordered thickness of 1.500 to 2.600 inches. The weldability of wrought aluminum alloy AA2139 armor has been determined for class I, type A armor for these thicknesses, only; 0.500” and 1.500”. The weldability for class I, type B and the other alloys (class II & class III) has not been determined and therefore should only be used as appliqué armor.
