SAE AMS 4100C:2000 pdf download Aluminum Alloy, Alclad, Sheet 5.7Zn – 2.2Mg – 1 .6Cu – 0.22Cr (Alclad 7475-T761 ) Solution and Precipitation Heat Treated
1 . SCOPE:
1 .1 Form:
This specification covers an aluminum alloy in the form of alclad sheet.
1 .2 Application:
This sheet has been used typically for structural applications requiring material with high strength and resistance to exfoliation-corrosion, moderate fatigue strength, and high fracture toughness, but usage is not limited to such applications.

3. TECHNICAL REQUIREMENTS:
3.1 Composition:
Shall conform to the percentages by weight shown in Table 1 , determined in accordance with AMS 2355 or MAM 2355.
3.2 Condition:
Solution and precipitation heat treated to the T761 temper in accordance with AMS 2772.
3.3 Properties:
Sheet 0.040 inch (1 .02 mm) and over in nominal thickness shall conform to the following requirements, determined in accordance with AMS 2355 or MAM 2355 on the mill produced product. Tensile properties, and fracture toughness requirements for sheet under 0.040 inch (1 .02 mm) in nominal thickness shall be as agreed upon by purchaser and vendor.
Alternate Testing for Demonstration of Fracture Toughness: When specified, the producer shall guarantee that sheet meets the fracture toughness requirements based on correlation of notch tensile strength/tensile yield strength (NTS/TYS) ratio, determined in accordance with 3.3.3.1 in lieu of fracture toughness testing (3.3.2). Sampling and test requirements, and lot acceptance criteria shall be as agreed upon.
