Recently, Chinese leading magnesium-lithium alloy and aluminum-lithium alloy supplier: ZZQY Light Alloy Technology Corporation issued an announcement:
The company successfully completed the development, mass production and delivery of 2195 aluminum-lithium alloy pre-stretched plates, with a width of 1200mm and a length of 6000mm, making it one of the few manufacturers in China that can deliver aluminum-lithium alloy ingots, forgings, profiles, and plates. unit.
The weight reduction of aviation and aerospace vehicles has reached the point of “calculating grams”. Designers continue to try various aspects from structural design to material replacement. Weight reduction has become an “eternal” goal in the development of aircraft.
As a representative of the third-generation aluminum-lithium alloy, 2195 aluminum-lithium alloy has smaller density, high strength, forgeability, weldability and low-temperature performance. It can replace 7075 and 2219 alloys for aerospace cryogenic storage tank materials.
The United States used 2195 aluminum-lithium alloy instead of 2219 aluminum alloy to manufacture Endeavour.
