CTIA’s TZM Alloy Screw

1. What's TZM Alloy Screw?
TZM Alloy Screw (Titanium Zirconium Molybdenum Alloy Screw) is a high-temperature precision fastening component manufactured through powder metallurgy using molybdenum (Mo) as the matrix with titanium (Ti: 0.40%–0.55%), zirconium (Zr: 0.06%–0.12%), and carbon (C: 0.01%–0.04%) additions to form TiC and ZrC dispersion-strengthened phases. Designed for small component fixation and precision assembly in high-temperature, vacuum, and thermal cycling environments, CTIA’s TZM alloy screw maintains excellent thread accuracy and reliable fastening performance during long-term service due to its superior high-temperature strength, creep resistance, and dimensional stability.

2. Advantages of CTIA’s TZM Alloy Screw
(1) High-temperature precision assembly capability: Offering a room-temperature tensile strength of 600–900MPa and excellent rigidity, the screw meets the load-bearing requirements of small fastening components under high-temperature conditions while reducing deformation and failure risks.

(2) Excellent thread dimensional stability: With a recrystallization temperature of approximately 1350–1450°C and a low coefficient of thermal expansion of 5.5–5.9×10⁻⁶/K, the screw minimizes thread dimensional changes during repeated heating and cooling cycles, maintaining assembly accuracy.

(3) High resistance to thermal loosening: Excellent creep resistance reduces preload loss under long-term thermal loads, allowing the screw to maintain reliable fastening performance during continuous operation.

(4) Compact installation adaptability: The compact structure and low weight of screw make it suitable for component fixation in space-limited areas, high-temperature chambers, and precision equipment.

(5) Excellent vacuum and high-temperature stability: With a high melting point of approximately 2620°C, low vapor pressure, and excellent structural stability at elevated temperatures, the screw is suitable for long-term use in vacuum environments.

3. Applications of CTIA’s TZM Alloy Screw
CTIA’s TZM alloy screw is mainly used in: (1) fixation of heat shields, heating components, and small structural parts in vacuum furnaces and high-temperature furnaces; (2) assembly of high-temperature chambers, wafer processing components, and precision parts in semiconductor equipment; (3) connection of high-temperature components in electron beam equipment and vacuum electronic devices; (4) heat-resistant fastening components in sapphire crystal growth furnaces and heat treatment equipment.

4. Specifications of CTIA’s TZM Alloy Screw
(1) Types: Cylindrical head screws, pan head screws, countersunk screws, socket head screws, and customized designs

(2) Dimensions: Customized diameters, lengths, thread specifications, and head dimensions

(3) Customization: Non-standard structures available
