Molybdenum rods have high melting points, good thermal conductivity, and low thermal expansion properties. At high temperatures, it can resist oxidation and has high strength. Molybdenum rods can be used to manufacture electric vacuum devices and electric light source components, as well as high-temperature heating elements, high-temperature structural components, electrodes, etc.
Production and processing procedures: molding, sintering, hanging forging, and machining.
classification
Classified by Material
① Pure molybdenum rod: with a molybdenum content greater than 99.95%.
② High temperature molybdenum rod (molybdenum lanthanum alloy rod): containing 0.4-1.2% lanthanum, with molybdenum content being the remainder except for impurities.
③ TZM molybdenum rod: 0.4~0.6Ti, 0.07~0.12Zr, 0.01~0.05C.
Classified by surface condition
① Sintered molybdenum rod: The surface has a silver gray metallic luster.
② Forging molybdenum rod: There is a layer of oxide on the surface, which is black in color.
③ Car gloss molybdenum rod: The surface has a metallic luster, smooth and rough.
④ Polishing molybdenum rod: It has a silver gray metallic luster, a smooth surface, and small dimensional errors.
