7005 O Aluminum
7005-O aluminum alloy is the version of 7005 aluminum in the annealed state. Compared to other 7005 series aluminum alloys, 7005-O aluminum has relatively lower strength but very high ductility. Its annealed state means that the alloy has a softer microstructure after being heated and slowly cooled, making it easier to form and weld during the processing.
7005-O aluminum alloy is commonly used in situations where good ductility and workability are required, especially in the manufacturing of structural components. For example, it is widely used in industries such as aerospace, transportation, and construction. Due to its lower strength, it is more often used for parts that do not require high strength but need higher toughness and formability, such as frames, connectors, and supports.
In addition, the excellent ductility of 7005-O aluminum alloy makes it perform well in processes such as deep processing, bending, and stretching. Despite its lower strength, its outstanding machining properties still make it competitive in many engineering applications.
