Mo-La Alloy

Molybdenum-lanthanum (Mo-La) alloy — pure molybdenum doped with 0.6–1.2% La₂O₃. The finely dispersed La₂O₃ particles pin dislocations, raising the recrystallization temperature and high-temperature creep resistance while lowering the ductile-brittle transition temperature, improving ductility and anti-sag performance. Supplied as rod Ø1–150 mm and plate 0.5–50 mm for petrochemical, energy, aerospace and high-temperature furnace applications.
