6、o 1.500 inches (1.02 to 38.10 mm), inclusive, in thickness, and produced with maximum cross sectional area of 23.25 in2 (15000 mm2) and a maximum circumscribing circle diameter (circle size) of 15.5 inches (394 mm) (see 8.4.1). 1.2 Application These extrusions have been used typically for structural
7、 aerospace applications requiring low density and high strength and stiffness combined with good corrosion resistance, but are not limited to these applications. 1.2.1 Certain processing procedures may cause this product to become susceptible to stress-corrosion cracking; ARP823 recommends practices
8、 to minimize such conditions. 2.
