Product Description

7149/7150/7249 Aircraft Aerospace Aluminum Extrusions Section for Aviation   

7149 aluminum alloy forgings profile

The 7149 is to reduce the content of Fe and Si impurities on the basis of 7049, to further improve the fracture properties of the alloy, and mainly to produce forgings. It has good strength and resistance to SCC, and the fracture property is better than 7049. It is a modified alloy with 7049. 7149 aluminum alloy forgings profile is mainly used in the forging parts of the main landing gear of the aircraft.

7249 aluminum alloy forgings profile

On the basis of 7149 alloy, the impurity content of Fe and Si can be reduced. Compared with 7249 T7651 and 7075 T7651, it has better resistance to peeling corrosion, stress corrosion resistance, fracture toughness and fatigue life, and is also convenient for heat treatment. 7249 aluminum alloy forgings profile is mainly used for the forging parts of the aircraft's main landing gear.
