Molybdenum Lanthanum MoLa Alloy Rod

Molybdenum Lanthanum alloy (Mo-La alloy) is an oxide dispersion strengthened alloy. Molybdenum Lanthanum (Mo-La) alloy is composed by adding lanthanum oxide in molybdenum. Molybdenum Lanthanum alloy (Mo-La alloy) is also called rare earth molybdenum or La2O3 doped molybdenum or high temperature molybdenum.

Molybdenum Lanthanum (Mo-La) Alloy 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.

Molybdenum-lanthana (MoLa) alloys are one type of ODS molybdenum-containing molybdenum and a very fine array of lanthanum trioxide particles. Small quantities of lanthanum oxide particles (0.3 or 0.7 percent) give the molybdenum a so-called stacked fiber structure. This special microstructure is stable at up to 2000°C.

High Recrystallization Temperature: The recrystallization temperature of MoLa alloy is significantly improved, typically ranging between 1400°C and 1500°C. This means that in high-temperature environments, the alloy maintains its structural integrity and does not become brittle like pure molybdenum, which undergoes recrystallization at lower temperatures.

High-Temperature Strength: At 1000°C, MoLa alloy achieves a tensile strength of 220 MPa with an elongation of 20%. This combination of high strength and good ductility ensures outstanding performance in high-temperature applications, enabling it to withstand significant mechanical stress.

Superior Creep Resistance: Creep is a common failure mode in high-temperature environments. MoLa alloy exhibits enhanced creep resistance, maintaining stable shape and dimensions under prolonged high-temperature and high-stress conditions, making it ideal for long-term high-temperature operations.

Excellent Oxidation Resistance

MoLa alloy performs exceptionally well in high-temperature oxidizing environments, effectively resisting oxidation. A dense oxide layer forms on its surface, preventing further oxidation and extending the material's service life. This oxidation resistance gives it a significant advantage in applications such as high-temperature furnaces and aerospace, where high-temperature durability is critical.

Good Ductility and Workability

Compared to pure molybdenum, MoLa alloy exhibits better ductility and is easier to machine and form. Its excellent ductility allows it to be processed into various shapes and sizes through cold drawing, cold rolling, and other techniques, meeting the needs of diverse applications.

Low Thermal Expansion Coefficient

MoLa alloy has a low thermal expansion coefficient, ensuring dimensional stability in high-temperature applications. This property helps minimize thermal stress caused by temperature fluctuations, thereby improving the reliability and service life of equipment.

Aerospace Applications

Rocket Nozzles: MoLa alloy's high-temperature strength and oxidation resistance make it an ideal material for manufacturing rocket nozzles. Operating under extreme high-temperature, high-pressure conditions, rocket nozzles must endure intense thermal stress and chemical corrosion, requirements that MoLa alloy meets effectively.

Thermal Shields: Used in aerospace engine thermal shielding components, MoLa alloy effectively protects sensitive internal parts from high-temperature radiation damage.

High-Temperature Structural Components: For critical parts such as turbine blades and combustion chambers, MoLa alloy withstands high temperatures and mechanical stress, ensuring the safe operation of aircraft.

High-Temperature Furnace Industry

Heating Elements: MoLa alloy rods are ideal for high-temperature furnace heating elements. Their high recrystallization temperature and oxidation resistance enable long-term stable operation in extreme heat, providing uniform heating performance.
