CTIA’s TZM Alloy Block

1. What's TZM Alloy Block?
TZM Alloy Block (Titanium Zirconium Molybdenum Alloy Block) is high-performance molybdenum-based alloy block with TiC and ZrC dispersion-strengthened phases. It uses molybdenum (Mo) as the matrix and incorporates titanium (Ti: 0.40%–0.55%), zirconium (Zr: 0.06%–0.12%), and carbon (C: 0.01%–0.04%) to form carbide strengthening phases. Through powder metallurgy process involving high-pressure compaction and vacuum sintering, followed by hot working, the strengthening phases are uniformly distributed within the molybdenum matrix, effectively improving high-temperature strength, creep resistance, structural stability, and long-term service reliability. CTIA’s TZM alloy block features high density, large cross-sectional load capacity, and excellent machining stability, making it suitable for high-temperature dies, vacuum thermal field equipment, and complex structural components.

2. Features of CTIA’s TZM Alloy Block
(1) High-temperature strength: Melting point of approximately 2620°C, with room-temperature tensile strength of 600–900MPa and reliable load-bearing capability above 1000°C.
(2) Creep resistance: TiC and ZrC dispersion-strengthened phases effectively inhibit dislocation movement and grain boundary sliding, improving long-term high-temperature stability.
(3) Structural stability: Recrystallization temperature of approximately 1350–1450°C, with suppressed grain growth and good dimensional stability at elevated temperatures.
(4) Thermal stability: Density of approximately 10.15–10.22g/cm³ and coefficient of thermal expansion of approximately 5.5–5.9×10⁻⁶/K, providing excellent thermal shock resistance.
(5) Machinability: Uniform microstructure and high density support turning, milling, grinding, drilling, and other precision machining processes for complex structural components.

3. Applications of CTIA’s TZM Alloy Block
