Aluminum 2024-T3 ist ein heat-treatable Al-Cu-Mg alloy mit strength approaching mild steel bei one-third der weight. Es ist der primär structural alloy für aircraft fuselage skins, wing tension members, und truck wheels. Sein major limitation ist poor corrosion widerstand — es ist almost immer used mit alclad coating oder chemical conversion protection.

Frequently Asked Questions
Warum ist 2024 immer alclad-coated für aerospace?
2024's hoch copper content (~4.4%) makes es highly susceptible zu galvanic corrosion und pitting. Alclad (ein thin layer von pure aluminum bonded zu der surface) provides cathodic protection. Ohne alclad, 2024 werden develop severe pitting innerhalb months von outdoor exposure.
