Form This specification covers an aluminum alloy in the form of extruded profiles with a maximum cross-sectional area of 25 in2 (160.29 cm2) and nominal thicknesses from 0.250 to 2.500 inch@ inclusive (6.3 to 63.50 mm@ inclusive). Application These extrusions have been used typically for machined parts requiring dimensional stability during machining processes@ high strength and damage tolerance@ but usage is not limited to such applications. Certain processing procedures may cause this product to become susceptible to stress-corrosion cracking; ARP823 recommends practices to minimize such conditions.
