Product Detail
Product Description
Molybdenum-lanthanum alloys, also known as high temperature molybdenum, are molybdenum alloys that are doped with rare-earth lanthanum to improve the high temperature properties of molybdenum and other properties. In order to improve the high temperature properties and working life of pure molybdenum used as a high temperature material, molybdenum is doped with lanthanum and other rare earths to increase the recrystallisation temperature of the material from 1000 to 1100°C to 1500 to 1600°C. The tensile strength at 20°C can reach 1400 MPa, which is reflected in the creep resistance of the material during use, thus greatly expanding the range of molybdenum materials used at high temperatures and This greatly extends the range and service life of molybdenum at high temperatures.
Specification molybdenum rare earth alloys such as molybdenum-cerium and molybdenum-lanthanum have better high-temperature properties than pure molybdenum, but also better electron-emitting properties, thus gaining application in the electronic information industry. Alloys with a lanthanum oxide content of 0.8% to 1.2% can be produced in bulk in the form of molybdenum-lanthanum alloy sheets, molybdenum-lanthanum alloy rods and various parts with the same dimensions and precision as pure molybdenum.
