There are some differences between TZM alloy rod and pure molybdenum rod in composition, performance and application. Here are the main differences between them:
Composition: TZM alloy rod is composed of alloy of molybdenum (Mo), titanium (Ti) and zirconium (Zr), among which molybdenum has the highest content, usually more than 99% in the alloy. The pure molybdenum rod is made of pure molybdenum, which contains more than 99.95% purity.
High temperature performance: TZM alloy rod has better performance in high temperature environment, in contrast, the high temperature performance of pure molybdenum rod is poor. TZM alloy rods can withstand higher temperatures and maintain structural stability and mechanical properties.
Strength and hardness: TZM alloy rods have higher strength and hardness, compared with pure molybdenum rods, which have lower strength and hardness. TZM alloy rods are suitable for applications requiring higher strength and wear resistance.
Radiation resistance: Due to the zirconium element in its composition, TZM alloy rods have better radiation resistance in radiation environments, and have higher radiation stability than pure molybdenum rods.
Corrosion resistance: TZM alloy rods have better corrosion resistance in corrosive environments. In contrast, pure molybdenum rods have poor corrosion resistance.
Cost: Compared with pure molybdenum rod, the cost of TZM alloy rod will usually be higher because it is a multi-element alloy and contains more alloying elements.
