2024铝板

凭借其相对良好的舒缓劳累性，特别是在厚钢板的形式，合金2024仍然是许多航空航天结构中指定的

2024铝板应用：2024不同的合金，如纯度较高的2124和2324，在改进强度及其他具体特点，还发现了在关键的飞机结构的应用程序

Alloy 2024 in the T351 and T851 tempers has not experienced any in-service problems with exfoliation.

In laboratory tests for exfoliation, alloy 2024-T851 material was essentially immune in any test plane.    

Stress Corrosion Cracking Resistance

In the T851 temper, alloy 2024 has very good resistance to SCC. Control of quenching and artificial

aging of 2XXX 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.
