DETAIL SPECIFICATION

ARMOR PLATE, ALUMINUM ALLOY, 2xxx, UNWELDABLE APPLIQUE

This specification is approved for use by the Department of the Army and is available for

use by all Departments and Agencies of the Department of Defense

1. SCOPE

1.1 Scope. This specification covers 2xxx wrought aluminum alloy armor plate for non

fusion welded applications in nominal thicknesses from 0.500 to 4.000 inch, inclusive

(see 6.2). The fusion weldability of 2xxx wrought aluminum alloy armor has not been

determined over this thickness range. Therefore, these alloys should only be used as

appliqué armor.

1.2 Classification. The wrought aluminum armor should be of the following classes and

tempers, as specified (see 6.2).

1.2.1 Class I. Wrought aluminum armor that conforms to the Aluminum Association

designation for the 2139 aluminum alloy in a T8 temper. The applicable gauge range for

Class I is 0.500-4.000 inches.

1.2.2 Class II. Wrought aluminum armor that conforms to the Aluminum Association

designation for the 2195 aluminum alloy in a T64 temper. The applicable gauge range for

Class II is 0.500-2.250 inches.

Comments, suggestions, or questions on this document should be addressed to: Director,

U.S. Army Research Laboratory, Weapons and Materials Research Directorate, Materials

and Manufacturing Technology Branch, Specifications and Standards Office, Attn:

RDRL-WMM-D, Aberdeen Proving Ground, MD 21005-5069 or emailed to

however, supersedes applicable laws and regulations unless a specific exemption has been

obtained.

3. REQUIREMENTS

3.1 First article. When specified in the contract or purchase order (see 6.2), first article

testing shall be required and all test samples required by this specification shall be made

available to the contracting officer or his authorized representative for approval in

accordance with 4.3. First article testing shall be completed before production material is

submitted for acceptance testing. The approval of the first article samples authorizes

commencement of production but does not relieve the supplier of the responsibility to

comply with all the applicable provisions of this specification. The first article samples

and acceptance test plates shall be manufactured by the process proposed for use on

production items.

3.2 Chemical composition. The chemical composition of the plates shall be within the

limits shown in Table I. The limits specified in Table I were taken from Aluminum

Association (AA) registered composition limits for Aluminum Alloys. A certification of

conformance of the chemical composition of the alloy shall be furnished with the ballistic

test plates.

3.3 Mechanical properties. Unless otherwise specified in the contract or order (see 6.2),

the mechanical properties of the test specimen taken in the longitudinal direction shall

meet the minimum mechanical properties listed in Table II. If mechanical property

requirements differ from those contained in Table II, or if any other properties are

required, the ballistic requirements shall be negotiated between the procuring activity and

the supplier.

3.4 Ballistic limit. The protection ballistic limit, BL(P), shall be as specified in

Appendix A. When a complete penetration can not be obtained for any class of armor
