6、osition (Table 1B), Condition (3.2), Properties (3.3.1.1), Reports (4.4.1) and Identification (5.1.1), and results from a Five-Year Review and update of this specification. 1. SCOPE 1.1 Form This specification covers an aluminum alloy in the form of sheet and plate, alclad both sides, supplied in th
7、e -T361 temper. 1.1.1 AMS4194 covers alclad material for sheet greater than 0.187 inch, and plate up to 0.500 inch (12.70 mm) in nominal thickness (see 8.5). The cladding thickness is minimized to provide a commensurate increase in tensile properties for this alclad reduction. Use of this product is
8、 not recommended without proper evaluation of corrosion resistance. 1.2 Supersession Notice Requirements for thin gage sheet (0.008 to 0.187 inch) in accordance with AMS4194 are hereby superseded by AMS4466. AMS-QQ-A-250/5 and AMS4466 have the same requirements for alclad thickness and tensile prope
9、rties for material less than 0.187 inch in thickness. 1.3 Application These products have been used typically for high strength parts requiring higher yield strength than is afforded by naturally aged tempers of this alloy and maximum corrosion resistance and whose fabrication does not involve weldi
10、ng, 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 forms a part of this specification to the extent specified herein. The supplier may work to a subsequent revision of a document unless a specifi
11、c document issue is specified. When the referenced document has been cancelled and no superseding document has been specified, the last published issue of that document shall apply.
