Molybdenum Lanthanum Alloy

Molybdenum Lanthanum Alloy consists of base molybdenum metal and trace lanthanum trioxide (La₂O₃), which is present in the matrix in the form of dispersed particles. The lanthanum oxide content of the alloy is typically 0.3%, 0.6%, and 1.1%. The addition of rare earth elements can not only improve the recrystallization temperature of molybdenum and high-temperature creep resistance but also significantly reduce the molybdenum plastic-brittle transition temperature, increasing the ductility. HM provides high-precision Mo-La alloy products in various forms, including rods, plates, sheets, tubes, wires, and custom parts, all crafted to ensure exceptional quality and customer satisfaction.
