2195 luminum lithium plate sheet is a light-weight, high-strength and corrosion-resistant metal structure material. It has a very broad application prospect in the aviation and aerospace fields. For every 1% of lithium added to the alloy, the density is reduced by 3%. Using aluminum-lithium alloy instead of the conventional aviation aluminum alloy can reduce the structural quality by 5%~15%, and the elastic modulus Increased by 10~16%, and increased rigidity by 15%~20%, to achieve lightweight aviation, aerospace weapons and equipment, to meet the development needs of its high-precision, ultra-long-range, ultra-high-speed strike. Features of
2195 aluminum lithium plate sheet: * Low density, for every 1% of lithium added, the density is reduced by 3%, the carrier is reduced by 1kg, and the launch cost is saved by about 20,000 US dollars * High specific modulus and high specific strength, replacing conventional high-strength aluminum alloy can reduce the structural quality by 10%-20%, increase the elastic modulus by 6%, and increase the rigidity by 15%-20% * Excellent corrosion resistance * Good thermal conductivity and electrical conductivity Good processing and formability (suitable for laser beam welding, friction stir welding, aging forming)
