Aluminum lithium alloy sheet has excellent mechanical properties and processing properties, and is mainly used in aircraft skins, aircraft tails, fuselage stiffeners, fuel tank compartments, rocket compartments and other fields. It can replace the current 2024, 2A12, 2A14, 7075, 7050, 7055 and other high-strength alloys. Under the premise of ensuring the same mechanical properties, it can reduce weight by 5% to 20%. It can meet the current urgent weight reduction needs of aircraft and has important economic and social benefit. Physical property of Aluminum lithium alloy sheet
