Product Description

Aluminum Alloy Extruded Seamless Tubes(7050/7075/7178)

7A04 7A09 7A15 7B05 aluminum tube pipe is a heat treatment and strengthening alloy of Al-Zn-Mg-Cu system. Its strength is higher than that of hard aluminum. It is characterized by its yield strength close to tensile strength and plasticity, and its sensitivity to stress concentration is strong, especially when subjected to vibration load and repeated static load. Therefore, the design of parts, the manufacturing process and the assembly process need to strictly avoid the stress concentration and the formation of additional stress. The heat resistance of the alloy is poor, and it will soften rapidly when the temperature is higher than 125, and the stress corrosion resistance of thick and thick parts is poor in short and transverse.

Ultra high strength Aluminum Alloy 7A09 alloy is Al-Zn-Mg-Cu, the strength of 7A09-T6 alloy 7A09 aluminum tube pipe is the highest, the aviation industry with one of the highest strength Aluminum Alloy deformation, the composition ratio of 7A04 alloy more superior performance, so it has better, get more extensive application in aircraft manufacturing, used in the manufacture of various important components of the force,7A09 aluminum alloy sheet round bar forgings have been widely used in aircraft, transport aircraft, and medium bomber trainer, for the production of the front landing gear, wing, fuselage connection frame, beam, pillar, partitions, floors, main beam joints and tail on the wall, the working cylinder hydraulic system, hydraulic oil tank of the movable rod inside and outside the tube, and other key components. Because of its high strength, the weight reduction effect is good and the safety of the aircraft is improved.

7B05 aluminum tube pipe is a relatively mature high purity aluminum alloy in China. It is a large aluminum alloy used on  aircraft in China. Parts of the machine account for 60% of the total aluminum alloy consumption, and the consumption of the single machine is about 20t, which achieves stable batch supply. Varieties include plates, thick plates, profiles, extruded panels, bars and forgings. The successful application of 7B04 alloy to  aircraft provides valuable experience for the promotion of domestic new materials in  civil aircraft.
