Description
🛡️ Premium TZM Molybdenum Rod – High-Temp Alloy Bar ASTM B387 Certified
🔍 Product Overview
The TZM Molybdenum Rod is a premium high-strength molybdenum alloy product designed for high-temperature structural and thermal applications. Engineered according to ASTM B387 Grade 364 standards, TZM (Titanium-Zirconium-Molybdenum) exhibits exceptional mechanical performance, outstanding creep resistance, and long-term dimensional stability at operating temperatures above 1300°C.
Whether you are building components for vacuum furnaces, aerospace tooling, or thermal shields, the TZM Molybdenum Rod offers a reliable and high-performance solution for demanding industrial environments.
🧪 What is TZM?
TZM is a molybdenum-based alloy containing:
-
Titanium (Ti): ~0.5%
-
Zirconium (Zr): ~0.08%
-
Carbon (C): ~0.03–0.05%
-
Molybdenum (Mo): balance
This alloy belongs to a class of refractory metals known for their extremely high melting points and structural integrity under heat and stress. The addition of Ti and Zr in TZM results in the formation of stable carbide precipitates (TiC and ZrC), which significantly enhance high-temperature strength, oxidation resistance, and grain stability.
