Electric Light Source Molybdenum Rod with High Melting Point ASTM B387 Standard
Molybdenum rods have high melting point, good thermal conductivity and low thermal expansion performance. They can be used to manufacture electric vacuum devices and electric light source parts. They can also be used as high-temperature heating elements and high-temperature structural parts, electrodes, etc.

Classification by material:
①Pure molybdenum rod: molybdenum content is greater than 99.95%.
②High-temperature molybdenum rod (molybdenum-lanthanum alloy rod): contains 0.4~1.2% lanthanum, and the molybdenum content is the remainder excluding impurities.
③TZM molybdenum rod: 0.4~0.6Ti, 0.07~0.12Zr, 0.01~0.05C.
Classification by surface state:
①Sintered molybdenum rod: the surface has a silver-gray metallic luster.
②Forged molybdenum rod: there is a layer of oxide on the surface, and the surface is black.
③Polished molybdenum rod: the surface has a metallic luster, flat and rough.
④Polished molybdenum rod: silver-gray metallic luster, smooth surface, small dimensional error
