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