A few days ago, the large-size aluminum-lithium alloy forgings used in high-end fields such as aviation and aerospace fields successfully rolled off the production line at HBHR Nuclear Equipment Technology Co., Ltd.
As the third-generation aluminum-based material, aluminum-lithium alloy has a lighter weight, significantly improved strength and elastic modulus compared to the first and second-generation aluminum-based materials, and will gradually replace China's first-generation aluminum-magnesium alloy and second-generation aluminum-copper alloy. Previously, only the United States and Russia had relatively mature manufacturing capabilities for large aluminum-lithium alloy forgings.
"This material is 3% lighter than pure aluminum, but after being extruded, its strength is increased by 6%, which is stronger than aluminum-copper alloys and aluminum-magnesium alloys, and has high added value.
The company's core products, large-diameter aluminum-lithium alloy bars and pipes, provide a strong guarantee for the high-precision and high-performance design and manufacture of aluminum alloy ring forgings with a diameter of 4 to 7 meters in China, and also lay a solid foundation for the development of the company's lightweight industry., Broaden the field of development.
