Aluminum 7050 AMS 4340

AMS 4340 is an aerospace material specification covering Aluminum Alloy 7050 supplied in extrusion form. The specification defines requirements for chemical composition, mechanical properties, heat treatment condition, dimensional tolerances, and inspection to ensure consistent performance in demanding aerospace and defense applications.

Aluminum 7050 extrusions are selected for applications requiring high strength, resistance to stress corrosion cracking, and reliable mechanical performance, particularly where extruded profiles are used in load-bearing or structural components. Compared to other high-strength aluminum alloys, 7050 provides improved durability and stability, especially in thicker or highly stressed sections.

Material supplied to AMS 4340 is commonly used in aerospace structural extrusions, fittings, and machined components where controlled processing and full traceability are required.

Tech Steel & Materials supplies AMS 4340 Aluminum 7050 extrusions with complete material certifications and traceability. Value-added services such as cut-to-length extrusions, machining support, and specialized packaging are available to meet program and shipment requirements.
