This specific material designates a wrought aluminum-copper alloy known for its high strength and machinability. The “2025” denotes the alloy composition, primarily aluminum with copper as the principal alloying element, along with smaller amounts of magnesium, manganese, and silicon. The “T3” designation indicates the material’s temper, achieved through solution heat treatment, cold working, and natural aging. This process enhances its mechanical properties, resulting in a material suitable for applications demanding both strength and ease of fabrication.
The combination of strength, machinability, and relatively low weight makes this material attractive for various applications, particularly in aerospace and structural components where performance and weight are critical factors. Historically, this material played a significant role in aircraft construction, demonstrating its reliability in demanding environments. Its favorable characteristics continue to make it a relevant choice for engineers and designers seeking robust yet workable materials.
