Types of Molybdenum Rod
Pure Molybdenum Rod
Pure molybdenum rods refer to molybdenum rods with a molybdenum content greater than 99.95%
High-temperature Molybdenum Rod
High-temperature molybdenum rods usually refer to molybdenum-lanthanum alloy rods, which contain 0.4-1.2% of lanthanum, and the molybdenum content is the balance except for impurities.
