Aluminum-lithium alloy is one of the most rapidly developed advanced lightweight structural materials in aerospace materials in recent years. It has many excellent comprehensive properties and is currently an important aerospace material that various countries are striving to develop.
Aluminum alloy has the advantages of light weight, high specific strength, corrosion resistance, etc. Since the world's first aircraft manufactured by the Wright brothers in 1903 used aluminum alloy casting engine crankcases, aluminum alloys have continued to follow the progress of the aviation industry. development of. Lithium is the lightest metal element. When lithium is added as an alloying element to metal aluminum, an aluminum-lithium alloy is formed.
The addition of lithium can reduce the specific gravity of the alloy, so that the aluminum-lithium alloy not only maintains the advantages of aluminum alloy, but also greatly improves its fatigue resistance and low-temperature toughness, so that the aluminum-lithium alloy has low density, high elastic modulus, and High strength and specific rigidity, good fatigue performance, corrosion resistance and welding performance and many other excellent comprehensive properties, have become the most rapidly developed advanced lightweight structural material in aerospace materials in recent years.
