The general organization of this series is described in EN 425
9、8. This standard has been prepared in accordance with EN 4500-2. I Scope This standard specifies the requirements relating to: Aluminium alloy AL-P2024- T351 Clad sheet and strip with improved chemical milling capability 1,6 mm sal 6 mm for aerospace applications. The material is manufactured to a m
10、inimum residual stress requirement for chemical milling applications. 2 Normative references This European Standard incorporates by dated or undated reference provisions from other publications.
