2124 Aluminum Plate Sheet
2124 Aluminum Plate
Sheet
Alloy 2124 T851
aluminum plate sheet was developed primarily for elevated temperature
applications requiring guaranteed fracture toughness and improved short
transverse properties, this plate sheet alloy also exhibits good strength
retention and creep resistance at elevated temperatures up to 177 ℃. Fracture
toughness levels of 2121 T851 plate sheet are substantially higher than 2024
T851.
Alloy 2124 T851
plate sheet is recommended for moderately elevated temperature application(
121-177 ℃) requiring better short-transverse ductility and fracture toughness
guarantees than are available with 2024 T851 plate. The primary use is machined
fuselage bulkheads and wing skins in high-performance military
aircraft.
Fracture
toughness is guaranteed for alloy 2124 T851 plate sheet(but not for alloy 2024
T851 plate) and shows more consistent values in different test directions than
2024 T851.
The fatigue
properties of alloy 2124 T851 are similar to those of 2024-T851.
Alloy 2124 T851
resistance to atmospheric corrosion is comparable to that of conventionally
fabricated 2024 T851. Test conducted on numerous lots of 2124 T851 show good
resistance to stress corrosion cracking, particularly in the short-transverse
direction. In 20 years of service there are no reported incidents of SCC
failures.
Alloy 2124 T851
aluminum plate sheet has excellent exfoliation corrosion resistance.
