2024 Aluminum Plate Sheet
2024 Aluminum Plate
Sheet
Alloy 2024
aluminum plate sheet is used in fuselage structurals, wing tension members,
shear webs and ribs and structural areas where stiffness, fatigue performance
and good strength are required. Sheet products usually alclad, are used
extensively in commercial and military aircraft for fuselage skins, wing skins
and engine areas where elevated temperature to 121 ℃ are often encountered.
Alloy 2024
aluminum plate and sheet in the T3 and T4 type tempers are noted for their
excellent toughness at moderately high strength levels.
All alloys of
the 2*** series are susceptible to atmospheric corrosion, especially in
industrial or seacoast atmospheres. These alloys should be protected, at least
on faying surfaces, when exposed to these conditions. Alcaldding these alloys
provides high resistance to atmospheric corrosion. The clad surface is resistant
to corrosive attack and also provides additional cathodic protection to the core
alloy.
Alloy 2014 in
the T351 and T851 tempers has not experienced any in-service problems with
exfoliation. In laboratory tests for exfoliation, alloy 2024 T851 materials was
essentially immune in any test plane.
In the T851
temper, alloy 2024 has very good resistance to SCC. Control of quenching and
artificial aging of 2*** high strength alloys that have been heat treated has
been effective in developing a high resistance to stress-corrosion cracking. In
over 20 years of service experience there have been no reported incidents of SCC
failures in 2024 T351 or 2024 T851 materials.
