Mo-La Alloy


Molybdenum lanthanum alloy (Mo-La alloy) is one of the Moly-REO alloy (molybdenum-rare earth oxide), it is also called rare earth molybdenum or La2O3 doped molybdenum. Molybdenum lanthanum alloy  is an oxide dispersion strengthened alloy.

Mo-La alloy is a useful and important molybdenum alloy composed by adding lanthanum oxide in molybdenum. It has the properties of higher temperature of recrystallization, better ductility, and excellent wear-resistant. Recrystallizing temperature of Mo-La alloy is higher than 1,500 degrees Celsius.
It can be used in illumination, electric vacuum device, tube component element in cathode-ray pipe, power semiconductor device, tool for manufacturing glass and glass fiber, internal part in light bulbs, high temperature heat shield, annealing Filament and Electrode, high temperature container and component in microwave magnetron.
Mo-La alloy sheet, plate, rod, bar and wire, machined parts for high temperature  furnace are available.
