一般腐蝕2XXX系列合金容易大氣腐蝕,特別是在工業(yè)或海岸環(huán)境。這些合金受到保護,至少在搭接面時,接觸到這些條件。 Alcladding這些合金提供高耐大氣腐蝕。 ţhecladsurfaceisresist antto腐蝕性的攻擊,并提供額外的
2024鋁板
憑借其相對良好的抗疲勞性,特別是在厚鋼板的形式,合金2024仍然是許多航空航天結構中指定的
2024鋁板應用:2024不同的合金,如純度較高的2124和2324,在改進強度及其他具體特點,還發(fā)現了在關鍵的飛機結構的應用程序
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. Cool 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.
