Recently, HJYJ Light Alloy Technology Group, a Chinese leading manufacturer of aluminum-lithium alloy structural parts, has successfully developed China's first 3.35-meter-diameter aluminum-lithium alloy storage tank for aerospace. It has been tested and tested in various links and has good performance, and initially has engineering application conditions. The storage tank uses the third-generation high-performance aluminum-lithium alloy. Compared with the current international mainstream aluminum-copper alloy storage tank, the strength is increased by about 30%, and the structure weight is reduced by more than 15% under the same conditions.
The aluminum-lithium alloy storage tank is the leading technology in the world
According to materials, there are the first generation aluminum-magnesium alloy storage tank, the second generation aluminum-copper alloy storage tank and the third generation aluminum-lithium alloy storage tank.
With the advent of the third generation of aluminum-lithium alloy storage tanks, a large area of aluminum-lithium alloy is used in the structure of the storage tank, which makes the structural efficiency and carrying capacity of China's aerospace industry reach the international leading level and represents the development direction of the aerospace industry storage tanks.
