(8118) - Clad aluminum alloys are used in aircraft because they
are naturally corrosion resistant, so they do not require corrosion resistant materials for
protection.
have surface layers of pure aluminum or aluminum alloy bonded to the core material to
inhibit corrosion.
are highly corrosion resistant because an oxide film forms on their surfaces upon contact with
air.

length of the rivets being used.
diameter of the rivets being used.
thickness of the material being riveted.
(8123)-Parts fabricated from Alclad 2024-T3 aluminum sheet stock must have all
bends made with a small radius to develop maximum strength.
bends 90° to the grain.
scratches, kinks, tool marks, nicks, etc., must be held to a minimum.
