Molybdenum has high heat resistance, good electrical conductivity, good thermal conductivity, and a low coefficient of thermal expansion. For this reason, molybdenum rods are widely used for heating elements and structural parts in high-temperature furnaces. Molybdenum rods are often used as electrodes in rare earth smelting and glass melting. Molybdenum and its alloy cores are also used in the manufacture of various small molybdenum crucibles, parts for molybdenum ion implantation, molybdenum parts for electric lights, and molybdenum castings. Molybdenum TZM alloys are base metal alloys consisting of a molybdenum matrix to which elements such as lanthanum, zirconium, titanium, niobium, and rhenium are added. TZM alloys are widely used for tools, molds, and high temperature components. Hot-drilled caps for seamless steel pipes using molybdenum TZM are widely used. Lanthanum molybdenum oxide alloys, in which pure molybdenum is alloyed with an appropriate amount of lanthanum oxide, are also called high-temperature molybdenum in the industry, effectively increasing the recrystallization temperature of molybdenum, reducing product deformation in a certain temperature range and improving service life.
