2、es.1. SCOPE1.1 FormThis specification covers an aluminum-lithium alloy in the form of extruded profiles with a maximum cross-sectional area of 19 square inches (123 cm2) and a maximum circle size of 11 inches (279mm) from 0.040 to 0.499 inches (1.00 to 12.50 mm) in thickness (See 8.5).1.2 Applicatio
3、nThese extrusions have been used typically for machined parts requiring high strength and good corrosion resistance, but usage is not limited to such applications.1.2.1 Certain processing procedures may cause this product to become susceptible to stress-corrosion cracking; ARP823 recommends practice
4、s to minimize such conditions.2.
