Strength standards and heat treatment process control for 2024 aluminum sheet for aerospace applications

Strength Standards: 2024-T3 aluminum sheet has a tensile strength of ≥470 MPa, a yield strength of ≥325 MPa, and an elongation of ≥10%, meeting the requirements of high-stress components such as aircraft skins and rivets.

Heat Treatment Process for 2024 Aluminum Sheet: Solution treatment (495-505°C) followed by artificial aging (120-150°C). Controlled holding time avoids overaging and ensures a balance between strength and ductility.

Process Control: Strictly monitor the heating rate (≤5°C/min) and cooling medium (water quenching) to prevent grain coarsening and stress concentration, ensuring material consistency.‌
