RATIONALE
This document has been reaffirmed to comply with the SAE 5-year Review policy.
NOTICE
This document has been taken directly from Federal Specification QQ-A-200/8F and contains only minor editorial and format changes required to bring it into conformance with the publishing requirements of SAE technical standards.
The original Federal Specification was adopted as an SAE standard under the provisions of the SAE Technical Standards Board (TSB) Rules and Regulations (TSB 001) pertaining to accelerated adopti
on of government specifications and standards. TSB rules provide for (a) the publication of portions of unrevid government specifications and standards without connsus voting at the SAE Committee level, (b) the u of the existing government specification or standard format, and (c) the exclusion of any qualified product list (QPL) ctions.
The complete requirements for procuring aluminum alloy 6061 bar, rod, shapes, tube, and wire extruded described herein shall consist of this document and the latest issue of AMS-QQ-A-200.

3.3Heat Treatment:
Unless otherwi specified in the contract or purcha order for T4, T4510, T4511, T6, T6510, and T6511 material, the producer may u an alternative heat treating procedure in lieu of a furnace heat
treatment covered by MIL-H-6088, provided the material conforms to all other requirements of this specification when sampled and tested in accordance with 4.2. The alternative heat treatment shall be performed on the whole of a piece, never on a part only, and shall be performed on the whole of a piece, never a part only, and shall be performed in a manner that will produce the utmost uniformity (See 6.2).
3.4Marking:
In addition to marking required by AMS-QQ-A-200, material in the T51, T6, T6510, and T6511
tempers and, when specified (See 6.2), material in the T1, T4, T4510, and T4511 tempers, shall also be identified by inspection lot number, marked in at least one location on each piece.
4.QUALITY ASSURANCE PROVISIONS:
See AMS-QQ-A-200 and the following:
4.1Heat Treatment:
4.1.1Aging Treatment Before Testing: Test specimens lected from material in the T1, T4, T42, T4510,
and T4511 tempers may be tested within 4 days following solution heat treatment. In the event of test failures caud by insufficient aging, retests shall be performed using material aged for 4 days or longer. Test specimens shall be prepared from the same coupons or location in the lot or lots from which the previously tested specimens were taken.
4.2Additional Sampling and Testing of Material Heat-Treated by Methods Not Covered by MIL-H-6088: 4.2.1Alloy Heat-Treated to the T6, T6510, or T6511 Tempers: When material in the T6, T6510, or T6511
tempers has not been heat-treated by a method covered by MIL-H-6088, internal quality controls shall be applied to establish that product so-treated meets all requirements of this detail
specification and AMS-QQ-A-200. Compliance with the requirements of Table II may be
determined by hardness tests followed by tension tests performed on samples from the two softest extrusions in the inspection lot. The method of hardness testing shall be left to the discretion of the producer.
4.2.2Alloy Heat-Treated to the T4, T4510, or T4511 Tempers: When material in the T4, T4510, or T4511
temper has not been solution heat-treated by a method covered by MIL-H-6088, internal quality controls shall be applied to establish that product so-treated meets all requirements of this detail specification and AMS-QQ-A-200. In addition, specimens taken from extrusions in the tempers shall be artificially aged to determine conformance to 3.2.2.2, as applicable, and be hardness-
tested and tension-tested in accordance with 4.2.1. Any specimen blank lected for an age-
hardenability determination shall be removed from the softest extrusion in the lot undergoing
inspection.什么是代理商
