Introduction of Molybdenum Bar
Brand: mo1, TZM, MoLa
Standard: GB / t4188-1984
Surface state: black, alkali washed, car polished, polished.
Usage: molybdenum bars are mainly used for manufacturing electric
vacuum parts, guide rods, electrodes, lead wires, high-temperature
parts, furnace heating rods, etc.

Classifications of Molybdenum Bars
Classification by material
1. Pure molybdenum rod: the molybdenum content is greater than
99.95%.
2. High temperature molybdenum rod (molybdenum lanthanum alloy
rod): it contains 0.4 ~ 1.2% lanthanum, and the molybdenum content
is the balance except impurities.
3. TZM molybdenum rod: 0.4 ~ 0.6 Ti. 07 ~ 012 Zr, 0.01 ~ 0.05C
Applications of Molybdenum Bars
① Molybdenum rod used for manufacturing electric vacuum devices and
electric light source parts.
② Molybdenum bar is suitable for processing ion implantation parts.
③ Molybdenum rod is used as high-temperature heater and
high-temperature structural parts.
4. Molybdenum rod is used as the electrode of furnace in glass and
refractory fiber industry, working in 1300 ℃ glass melt, long life
⑤ Molybdenum bar is used as an electrode in the industry.
Molybdenum customized parts according to drawings are
available.
