WHAT IS 7050 ALUMINUM USED FOR?
7050 aluminum is mainly used for high-strength structural applications where excellent toughness, fatigue resistance, stress corrosion resistance and dimensional stability are required. As a high-performance 7000 series aluminum alloy, 7050 aluminum is widely used in aerospace, defense, aircraft structural components, high-strength molds, precision machining parts, transportation equipment, and industrial engineering applications.
What Is 7050 Aluminum?
7050 aluminum is a high-strength aluminum-zinc-magnesium-copper alloy belonging to the 7000 series. The main alloying elements include zinc, magnesium, copper and zirconium, which provide high tensile strength, fracture toughness and stress corrosion cracking resistance. 7050 aluminum is usually supplied in heat-treated tempers such as T7451, T7651, and T7351 for aerospace or industrial use.
Common Product Forms of 7050 Aluminum
- 7050 Aluminum Plate: Used in aircraft bulkheads, wing components, frame structures, high-strength tooling plates.
- 7050 Aluminum Sheet: Used for aerospace panels, structural skins, high-performance industrial components.
- 7050 Aluminum Bar: CNC machining, aerospace fittings, shafts, connectors, high-strength structural components.
- Forged & Machined Parts: Critical aerospace, defense, tooling and precision engineering applications.
