Industry knowledge

There are various surface conditions of molybdenum rod.

There are various surface conditions of molybdenum rod. According to its polishing condition, black and polished molybdenum rod can be divided. When considered its state condition, coiling and straightened molybdenum rods are different. To its making method, forged and grind molybdenum rods can be told apart. While heat Treatment is taken in consideration, molybdenum rods have drawn and annealed types. During its manufacturing, molybdenum rods should comply with the content table as Chinese national standard -- GB4188-84, as followed.

Besides pure molybdenum rods, alloy molybdenum rod is also manufactured. For example, lanthanated doped molybdenum rod (Mo-La Rod), which is targeted for using in higher temperature applications where ductility is retained after recrystallization for material with smaller cross sections.
