scope:
This specification covers two wrought aluminum armor plate alloys for welded and nonwelded applications in nominal thicknesses from 0.500 to 4.000 inch, inclusive (see 6.2). The weldability of wrought aluminum alloy AA7017 armor has been determined for Class I armor for these thicknesses, only; 1.000" and 1.500". Class I (AA7017) material is a direct replacement for MIL-DTL-46063H w/Amendment 2 material, namely AA7039 for new design and if specified (see 6.2), for old design or repair/replacement. The weldability of wrought aluminum alloy AA7020 armor has been determined for Class II armor for these thicknesses, only; 1.000" and 1.500".
Weldability. The material covered by this specification has been demonstrated to be weldable to itself and other weldable alloys (see 6.4).
Classification. The wrought aluminum armor should be of the following classes, as specified (see 6.2).
Class I. Class I is wrought aluminum armor that conforms to the Aluminum Association designation for the 7017 aluminum alloy. The applicable gauge range for Class I is 0.500 - 4.000 inches.
Class II. Class II is wrought aluminum armor that conforms to the Aluminum Association designation for the 7020 aluminum alloy. The applicable gauge range for Class II is 0.500 - 4.000 inches.
intended Use:
The armor specified herein is intended for use on combat and tactical vehicles to protect the occupants against small arms fire, fragments, and shrapnel. Class II (AA7020) has better inherit... View More
