Molybdenum Lanthanum Alloy Rod
1. Description of Molybdenum Lanthanum Alloy Rod:
Molybdenum-lanthanum alloy, also known as high-temperature molybdenum, grade MoLa, is a so-called laminated fiber structure formed by doping a small amount of lanthanum trioxide (La2O3) particles in molybdenum. This special microstructure remains stable at temperatures up to 2000°C. Therefore, molybdenum-lanthanum oxide has creep resistance even under service conditions. We mainly process these molybdenum alloys into high temperature furnace components such as vacuum furnace heat shields, heating body bars, sintering and annealing boats, stranded wires or evaporator coils.

5. Application of Molybdenum Lanthanum Alloy Rod:
Sintering Molybdenum Lanthanum alloy rod, as the raw material, is mainly used in pulling Molybdenum wire and Forging Molybdenum rod. As Molybdenum possesses the feature of melting point, forging Molybdenum lanthanum alloy rod with high purity, Electrodes, screws, heating elements in high-temperature furnaces, rabbles in the rare earth smelting industry, heating electrodes in the glass industry, and lamp supports in the lighting industry, among other materials, are frequently used because of their high density and excellent high-temperature proof of creep deformation.
