7A09 Aluminum Sheet

7A09 Aluminum Sheet Product Introduction

7A09 aluminum sheet is Al-Zn-Mg-Cu alloy, which is an ultra-high strength deformed aluminum alloy that has been used in the aircraft industry in the late 1940s and is still widely used in the aviation industry. 7A09 aluminum sheet is used in the aerospace industry with high strength, good weight reduction, and improved aircraft safety.

All our products are manufactured with advanced equipment and strict QC procedures in order to insures every product's high quality. 18 years of experience in the source manufacturers, we can supply competitive price. Sample can be provided as per your requirements for free.

We also offer 7A04 aluminum sheet,7050 aluminum sheet,7075 aluminum sheet, and other types for you to choose from.

7A09 Aluminum Sheet Advantages

1. The heat treatment strengthening effect is particularly good, with high strength below 150 ℃, and particularly good low temperature strength.

2. High ratio strength, good fracture toughness and thermal conductivity.

3. The plasticity after solution treatment is good. The plasticity under annealing and just quenching temper is slightly lower than that of 2A12 aluminum sheet with the same temper, and slightly better than 7A04.

4. Poor welding performance. Prone to stress corrosion cracking, unless under T6 temper.

Aluminum Sheet Series Introduction

7A09 Aluminum Sheet Mechanical Properties

• Tensile strength σb (MPa): ≥530
• Conditional yield strength σ0.2 (MPa): ≥400
• Elongation δ10 (%): ≥6

Packaging of Aluminum Sheet

Yongsheng aluminum sheet is placed on a wooden pallet or wooden box, wrapped perfectly with waterproof craft paper, and then fixed with a narrow strip of iron.

Usually, we have six layers of packing: put on wooden supports and put desiccant, wrap moisture-proof film, wrap the plastic film, wrap the moisture-proof cotton, wrap the plastic moisture-proof film again and pack it with cardboard.

7A09 Aluminum Sheet Application

7A09 aluminum sheet is widely used in the aviation industry and used to manufacture various important parts.

7A09 aluminum is used for aircraft skins, wall panels, bulkheads, front beams, ribs, joints, pillars and landing gear, cylinder hydraulic systems, hydraulic oil tanks with movable rods, outer tubes and other key components. The light weight of aluminum can reduce the weight of the aircraft, but this does not affect the safety of the aircraft, and it can even be improved.
