High Temperature Molybdenum Lanthanum (MoLa) Alloy Rod

Short Description:

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.
