Product introduction

After twenty-first Century, aluminum alloy materials used in aerospace industry are mainly used as structural materials on aircraft, such as skin, frame, wall plate and landing gear. The strength of 7A09 aluminum alloy plate is high, and 2A12 alloy is slightly inferior to that of 7A04 alloy under annealing and quenching. It is slightly better than that of 7A04 alloy. The static fatigue, notch sensitivity and stress corrosion cracking properties of 7A09 alloy plate are slightly better than those of 7A04 alloy, and the properties of bar are similar to those of 7A04 alloy. The 7075 aluminum alloy Aeronautics and Astronautics supplied by the aluminum and aluminum industry are all derived from the China aerospace aluminum material support base, which has formed a complete system of aerospace R & D and production. It has reached the standard of American aerospace standards through Boeing, Chinese commercial flight, peak racing and Airbus certification.

Technical parameter














The packing method of aluminum plate:

1. Foil or laminating the aluminum sheet to ensure that the surface of the aluminum sheet is intact without scratching.

2, the plastic or kraft paper package is used to prevent moisture and rain, to ensure that the aluminum plate is clean and free of dirt during the transportation process (each package has moistureproof desiccant to ensure the quality of our products in East China and Southern China).

3, add wooden support and steel belt reinforcement to avoid collision in transportation process and ensure aluminum plate geometry unchanged.

4. Export products are packed in wooden boxes and brackets with fumigation marks.

5, packaging according to other packaging requirements of customers.

The packing method of the strip:

1. When the width of the strip is not larger than 500mm and the coil diameter is not greater than 500mm, after wrapping 1~2 layers of kraft paper outside, it will be packed with adhesive label.

2, when the width of the strip is not more than 500mm and the roll diameter is more than 500mm, the outer layer is wrapped with bamboo sheet, fiber board or cardboard after wrapping 1~2 layers of kraft paper and a layer of plastic cloth, and the vertical or horizontal tray is packaged in series, and the vertical (or lying) tray is used.

3, when the width of the strip is greater than 500mm and the roll diameter is more than 500mm, the 1~2 layers of kraft paper and a layer of plastic cloth are wrapped, and the outer layer is packed with a bamboo mat, or the fiberboard is wrapped by a vertical or horizontal tray frame.

Product application

7A09 aluminum alloy has high thermal plasticity, heat treatment, heat resistance, impact toughness, fatigue property and weldability. It is mainly used in aerospace aluminum alloy thick plate, airspace wing beam, helicopter heterosexual hollow rotor beam and aircraft runway, aircraft wallboard, joint, support and landing gear and other structural parts, civil pens and so on. Remember the shell and so on.
