Shandong Mannesmann Metal Products Co., Ltd

　　MannesmannAluminum Industry Group has the ability to provide high-end aluminum iron materials for the aviation industry, with a wide variety of products. Some military standard products, such as new engine turbine discs, compressor discs, and blade aluminum, have been successfully applied in the production of core components such as "Flying Leopard", "J-10", bombers, and assault aircraft. At the same time, Mannesmann Aluminum provides military aluminum materials for important components of rocket engines, making contributions to the development of China's aerospace industry.

　　Aluminum alloy has a series of advantages such as low density, high specific strength, good corrosion resistance, and excellent formability, which make it an important material for aerospace. Mainly used for structures such as fuselage skins, wing and stabilizer skins, fuselage frames, fuel tanks, and connectors.

　　Through the application of aluminum alloy composite materials, the density of the shell materials on aerospace vehicles can be reduced by 5% - 7%, the material stiffness can be increased by 7%, and the weight can be reduced by 10%, so as to improve the fuel efficiency. At the same time, because of the corrosion resistance, good fatigue resistance and Damage tolerance of aluminum alloy materials, the inspection interval time can be extended, and the maintenance cost of spacecraft can be reduced.

　　Lower capital cost: Aluminum alloy has a certain price advantage over steel.

　　Typical alloys such as 2024, 7075, 7475, 7050, 7150, etc.

　　Product features: high strength, high toughness, high resistance to Damage tolerance.
