Molybdenum Lanthanum (Mo-La)

Molybdenum-lanthanum (MoLa) is an oxide-dispersion strengthened molybdenum alloy comprised of molybdenum (Mo) and lanthanum trioxide (La₂O₃) and often used in vacuum furnaces or other high heat applications due to its dimensional stability and creep resistance at temperatures above 1800ºC.

Our MoLa alloy contains 0.3%-1.2% of La₂O₃. MoLa0.7% is the common used alloy for customers. It has been demonstrated that doping molybdenum with lanthanum trioxide particles could enhance the strength and creep resistance behavior at elevated temperature. Pure molybdenum tends to be brittle at high temperature but MoLa gains higher recrystallization temperature and creep resistance, and therefore could have a longer service time at elevated temperature.

MoLa alloy is typically supplied in sheets, plates, wires, furnace parts such as heating elements, stranded wires and boats for sintering and annealing.
