Aluminium–lithium (Al–Li) alloys are being used more frequently in the A/C industry on all metallic parts such as actuator and hinge fittings, for which the fatigue and damage tolerance criteria are important. Al–Li alloys are lighter and have high tensile and yield strength compared to the conventional high-strength aluminium alloys.
Aluminum-Lithium Alloys. However, the binary aluminum lithium alloys show limited ductility and toughness, and other elements such as Mn and Zr, are added with the objective to form dispersoids, and Cu and Mg are added to form precipitated phases that provide more strength to the alloy, stabilize the microstructure and limit the formation of precipitated free zones, which have a detrimental ...

作者: C. Baker, P. J. Gregson, S. J. Harris2018-3-1 The superior properties of the Al-Li alloys are mainly attributed to the added Li, which influences the weight reduction and elastic modulus. As previously reported, 1 wt% of Li decreases the density of the resultant Al alloy by approximately 3% and increases the elastic modulus by approximately 6%, as depicted in Fig. 2a and b, respectively , , .

2020-10-2 Aluminium–lithium alloys (Al-Li) are a series of alloys of aluminium and lithium, often also including copper and zirconium.Since lithium is the least dense elemental metal these alloys are significantly less dense than aluminium. Commercial Al–Li alloys contain up to 2.45% by weight of lithium. Alloying with lithium reduces structural mass by three effects:
