Hot Runner TZM Bar

Hot Runner TZM Bar is a titanium-zirconium-molybdenum (TZM) alloy rod used in hot runner systems. TZM alloy is made by adding small amounts of titanium (Ti), zirconium (Zr), and carbon (C) to a molybdenum base. It is produced through powder metallurgy.This alloy rod usually has a silver-gray metallic shine. It comes in different processed forms, such as sintered, forged, turned, alkali-washed, ground, and polished.

TZM has an extremely high thermal conductivity of 140W/mK, and has excellent high temperature performance, corrosion resistance and processing mechanical properties, which can meet the requirements of hot runners for long-term use at high temperatures, and can be made into nozzles of different shapes for use in hot runner systems.

TZM has good mechanical properties at high temperature and pressure so widely used in military fields, such as the valve body of torpedo engine, rocket nozzles, gas pipes and nozzles roar lining. TZM could be made in different shapes, such as TZM alloy electrode, rod, plate, disc, bar, sheet, foil, crucible, boat, tube, and so on.

Excellent High-Temperature Performance: TZM alloy has a high melting point (about 2620°C), high boiling point, and low vapor pressure, so it stays stable in high-temperature environments.

High Strength & Good Toughness: The alloy is strengthened by solid solution and second-phase reinforcement, giving it high strength and good low-temperature ductility.

Strong Creep Resistance: The added titanium and zirconium greatly improve the alloy's creep resistance, preventing deformation at high temperatures.

Good Thermal Conductivity: TZM alloy conducts heat well, ensuring even temperature distribution in hot runner systems.

Strong Corrosion Resistance: The alloy resists corrosion effectively at high temperatures and can withstand many chemical substances.

Hot Runner System Components: TZM alloy bars are widely used to make nozzles, bushings, manifold plates, and heating elements in hot runner systems. These parts work in high-temperature and high-pressure conditions, and TZM alloy's heat resistance and wear resistance make it an ideal material.

Injection Molds: In plastic injection molding, TZM alloy bars can be used to make high-temperature mold parts like hot runner nozzles and gate sleeves. This helps improve production efficiency and reduce waste.

Aerospace & Military Applications: Thanks to its high-temperature strength and corrosion resistance, TZM alloy is also used in aerospace and military fields for high-temperature structural materials.

High-Temperature Heat Treatment Equipment: TZM alloy bars can be used to make heating elements, clamps, and heat shields in high-temperature heat treatment equipment.

What are the key properties of TZM alloy?

High-temperature stability

Strong creep resistance

Good thermal conductivity

High strength and toughness

Corrosion resistance

What components are made from TZM bars in hot runner systems?

Common parts include nozzles, manifold plates, heating elements, and gate sleeves that require heat and wear resistance.

How does TZM compare to pure molybdenum?

TZM has better strength, creep resistance, and high-temperature stability than pure molybdenum due to titanium (Ti) and zirconium (Zr) additions.

Can TZM alloy be machined easily?

Yes, but it requires specialized tools due to its hardness. Common processes include turning, grinding, and polishing.

What industries use TZM alloy bars?

Plastic injection molding (hot runners)

Aerospace & defense
