DETAIL SPECIFICATION
ARMOR PLATE, ALUMINUM, ALLOY 7017 WELDABLE and 7020 APPLIQUE
This specification is approved for use by the Departments and Agencies of the Department of
Defense
1. SCOPE
1.1 Scope. This specification covers two wrought aluminum armor plate alloys for welded and
non-welded 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 acceptance requirements and the weldability of
wrought aluminum alloy AA7020 armor have not been determined for Class II armor prior to the
publication of this specification. Current testing is on-going and when completed this specification
will be revised to contain all pertinent requirements and conditions for Class II (AA7020) armor.
Class II aluminum alloy AA7020 is listed in this specification as a place holder until the above
mentioned testing program is completed. Tables will be populated with the AA7020 requirements;
however, for now the values will be replaced with `TBD' (to be determined).
1.2 Weldability. The material covered by this specification has been demonstrated to be weldable to
itself and other weldable alloys (see 6.4).
1.3 Classification. The wrought aluminum armor should be of the following classes, as specified
(see 6.2).
