SAE AMS 4078F pdf download.Aluminum Alloy Plate (7075-T7351) Solution Heat Treated, Stress Relieved, and Overaged.
1.1 Form:
This specification covers an aluminum alloy in the form of plate.
1.2 Application:
This plate has been used typically for machined parts subject to excessive warpage during machining due to residual stresses and for parts requiring high strength and resistance to stress- corrosion cracking, but usage is not limited to such applications.
2. APPLICABLE DOCUMENTS:
The issue of the following documents in effect on the date of the purchase order form a part of this specification to tlie extent specified herein. The supplier may work to a subsequent revision of a document unless a specific document issue is specified. When the referenced document has been canceled and no superseding document has been specified, the last published issue of that document shall apply.

3.3.2 Corrosion Resistance: Resistance to stress corrosion cracking and to exfoliation-corrosion shall be acceptab4e if the plate conforms to 3.3.2.1 or 3.3.2.2.
3.3.2.1 If electrical conductivity is not lower than 38.0% IACS (International Annealed Copper Standard) (22.0 MS/rn), determined on the surface of specimens used for tensile testing.
3.3.2.2 If electrical conductivity is 38.0 to 39.9% (22.0 to 23.1 MS/rn) inclusive, and yield strength does not exceed the specified minimum by more than 11.9 ksi (82 MPa).
3.3.2.3 lIthe requirements of 3.3.2.1 or 3.3.2.2 are not met, the plate may be given additional precipitation heat treatment or re-heat treated. If, after such treatment, all specified properties are met, the plate is acceptable.
3,3.2.4 If the conductivity is below 38.0% lAGS (22.0 MS/rn), the product is not acceptable and must be reprocessed regardless of tensile property load.
3.3.3 Stress-Corrosion Resistance: Specimens cut from plate 0750 inches (19.05 mm) and over in nominal thickness shall show no evidence of stress-corrosion cracking when stressed in the short- transverse direction to 75% of the applicable minimum yield strength specified In 3.3.1.
3.4 Quality:
Plate, as received by purchaser. shall be uniform in quality and condition, sound, and free from foreign materials and from imperfections detrimental to usage of the plate.
3.4.1 When specified, each plate 0.500 inch (12.70 mm) and over in nominal thickness shall be ultrasonically inspected in accordance with ASTM B 594 and shall meet the requirements of 3.4.11 or 34.1.2 as applicable.
3.4.1.1 Plates weighing 2000 pounds (907 kg) and under shall meet the requirements for ultrasonic class shown in Table 3.
4. QUALITY ASSURANCE PROVISIONS:
4.1 Responsibility for Inspection:
The vendor of plate shall supply all samples for vendor’s tests and shall be responsible for the performance of all required tests. Purchaser reserves the right to sample and to perform any confirmatory testing deemed necessary to ensure that the plate conforms to the specified requirements.
4.2 ClassificatIon of Tests:
4.2.1 Acceptance Tests: Composition (3.1), tensile properties (3.3.1), conductivity (3.3.2), tolerances (3.5), and, when specified, ultrasonic soundness (3.4.1) are acceptance tests and, except for composition, shall be performed on each lot.
4.2.2 Periodic Tests: Stress-corrosion resistance (3.3.3) is a periodic test and shall be performed at a frequency selected by the vendor unless frequency of testing is specified by purchaser.
4.3 Sampling and Testing:
Shall be in accordance with AMS 2355 or MAM 2355.
4.4 Reports:
The vendor of product shall furnish with each shipment a report stating that the product conforms to the chemical composition, tolerances and NDT inspection, when required, and showing numerical results of tests for the other acceptance test requirements and periodic test requirements when performed. This report shall include the purchase order number, inspection lot number(s), AMS 4078F, size, and quantity. The report shall also identify the producer, the product foi’m. and the size of the mill product.
