What Are Aluminum‑Lithium Alloys?
Aluminum‑lithium alloys are engineered by blending aluminum with small amounts of lithium, typically 1–4 % by weight. The lithium addition lowers density by up to 10 %, while simultaneously enhancing stiffness‑to‑weight ratio, fatigue life, and resistance to corrosion. These attributes make the alloys especially attractive for components that demand a high strength‑to‑weight ratio, such as aircraft skins, fuselage frames, satellite structures, and electric‑vehicle chassis.
