Product introduction

It is used to manufacture aircraft structure and other high stress structures with high strength and high corrosion resistance, such as upper and lower wing panels, stringer, frame, etc. After solid solution treatment, the plasticity is good, the effect of Tsinghua heat treatment is especially good. It has high strength below 150 C, and has a special low temperature strength. The double stage aging can improve the anti SCC performance. 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

It is mainly used in the aeronautics and space industry, the upper wing structure of the large airliner, the stiffener of the fuselage, the upper wing of the aircraft, the panel of the lower wing, the plate of the radiator (the aluminum foil and the thin strip of the air conditioner, the coating of the alloy plate and the tube).
