NONCURRENT NOTICE This specification has been declared “NONCURRENT” by the Aerospace Materials Division, SAE, as of January 2008. It is recommended, therefore, that this specification not be specified for new designs. “NONCURRENT” refers to those specifications which have previously been widely used and which may be required for production or processing of existing designs in the future. The Aerospace Materials Division, however, does not recommend these specifications for future use in new designs. “NONCURRENT” specifications are available from SAE upon request. Similar but not necessarily identical products are covered in the following specifications. However, this listing is provided for information only and does not constitute authority to substitute these specifications for the “NONCURRENT” specification.

QUALITY ASSURANCE PROVISIONS: See AMS-QQ-A-200 and the following: 4.1 Heat Treatment: 4.1.1 Aging Treatment Before Testing: Specimens selected for treatment to T4, T42, T4510, and T4511 tempers may be tested within 4 days after completion of the solution heat treatment. If these tests fail, the manufacturer may elect to test additional specimens from the same sample lot after the expiration of at least 4 days after the date of solution heat treatment. These specimens shall be taken from the same location in the lot as the prior specimens. 4.2 Mechanical Test After Heat Treatment: 4.2.1 Number of Tests After Heat Treatment: From material in each temper of those specified for heat treatment capability demonstrations in 3.2.2 and 6.2, an additional number of specimens equal to that required in AMS-QQ-A-200 shall be taken and tested after heat treatment to each temper specified to determine conformance to 3.2.2. 5. PREPARATION FOR DELIVERY: See AMS-QQ-A-200. 6. NOTES: 6.1 Intended Use: This alloy is intended for use where high strength is required, usually no welding is involved, and where optimum corrosion resistance is not required. The T4510 and T6510 tempers are intended primarily to provide extruded material with low residual stresses and consequent minimum distortion during machining. The T4511 and T6511 tempers are straightened T4510 and T6510 material, respectively, and may have unknown residual stresses and may or may not distort during machining. - - ` , ` , ` , , , ` ` , ` ` , ` ` ` ` , , ` , , ` , , ` , , , - ` - ` , , ` , , ` , ` , , ` - - - AMS-QQ-A-200/2A SAE AMS-QQ-A-200/2A - 8 - 6.2 Ordering Data: Purchasers should select the preferred options permitted herein and include the following information in procurement documents: Title, number, and date of this specification. Form, quantity, and temper required (See 1.2.1). Dimensions required. Mechanical properties and dimensional tolerance requirements for sizes not specifically covered. Demonstrations of heat treatability of material in tempers other than the O temper (See 3.2.2 and 4.2.1). Whether ultrasonic inspection of bar, rod, and shapes is required (See 3.3). Special end use requirements. Selection of applicable levels of preservation and packing, whether Level A, Level B, or commercial (See AMS-QQ-A-200). Whether lot numbering for material in the T4, T4510, or T4511 tempers is required. Whether Type I tubing is required (See 1.2.2). 6.3 Properties After Heat Treatment: Mechanical properties and corrosion properties, where applicable, are certified for the temper of material supplied. The producers capability demonstration is not evidence that user-treated material conforms to property requirements of a given temper. Frequently, user-heat-treated material may develop a lower level of properties, especially if any cold, warm or hot work is introduced, prior to solution heat treatment. The user should be held responsible for demonstrating that his processing will yield properties meeting requirements. 6.4 Product produced and marked to the requirements of AMS-QQ-A-200/2 also meets the requirements of QQ-A-200/2F. Product produced and marked to the requirements of QQ-A-200/2F also meets the requirements of AMS-QQ-A-200/2. 6.5 The properties listed in 3.2.1 are exactly the same as QQ-A-200/2, Revision F. These properties have not been substantiated in accordance with the Manual for Preparation of Aerospace Specifications.
