Abstract

Alcoa extrusion alloy 2026 was developed as an improvement over 2024 and 2224 extrusions in aerospace structural applications where the governing selection criteria are high damage tolerance, good fatigue resistance, and a high degree of manufacturability. In addition to improved damage tolerance, extrusion alloy 2026-T3511 also has a significantly higher A-basis minimum strength than 2024-T3511 and 2224-T3511. This datasheet provides information on composition, tensile properties, and compressive strength as well as fatigue. It also includes information on corrosion resistance as well as forming. Filing Code: AL-401. Producer or source: AEAP-Alcoa Engineered Aerospace Products.
