Key Features
Tantalum Tube delivers 99.9% purity tantalum in a precision hollow form, combining dimensional accuracy, aggressive-environment durability, and vacuum stability for heat transfer, semiconductor, medical, and high-vacuum applications:
Precision Hollow Form for Heat Transfer & Flow Applications
The hollow cross-section makes Tantalum Tube the natural choice for acid-service heat exchangers, where corrosion-resistant tubing transfers heat between aggressive process streams without degradation, and for thermowells and thermocouple sheaths in high-temperature reactors and furnaces where dimensional accuracy and chemical inertness are both required.
Exceptional Corrosion Resistance in Aggressive Media
Tantalum Tube resists attack from virtually all acids and aggressive chemical environments, supporting its use as flow liners in reactive-gas delivery systems and structural components in plasma etching chamber assemblies in semiconductor manufacturing, where standard tube materials would be rapidly degraded by process chemistry.
High-Temperature Stability (Melting Point 3,017 °C)
With a melting point of 3,017 °C, Tantalum Tube maintains its dimensional integrity and corrosion resistance as thermowells and thermocouple sheaths in high-temperature reactors and furnaces, where combined thermal and chemical exposure would compromise tubes made from less refractory materials.
Low Vapour Pressure & Vacuum Stability
Tantalum Tube's low vapour pressure and vacuum stability make it well suited to discharge and shielding components in high-vacuum systems, where outgassing or vapour evolution from tube materials would contaminate the vacuum environment or degrade system performance.
Biocompatibility for Medical Implant Applications
Tantalum Tube's biocompatibility and resistance to body fluids support medical implant applications where a hollow cylindrical geometry, chemical inertness in physiological environments, and long-term compatibility with biological tissue are all required in the implanted component.
Industrial Applications
Tantalum Tube is used across chemical processing, semiconductor, medical, and high-vacuum sectors where a precision hollow form combining corrosion resistance, thermal stability, and vacuum compatibility is required:
- ✦ Acid-Service Heat Exchangers
- Used as corrosion-resistant tubing in acid-service heat exchangers, where Tantalum Tube transfers heat between aggressive process streams without degradation — providing reliable long-term performance in the highly corrosive environments encountered in chemical and pharmaceutical processing where standard metallic tubing would fail.
- ✦ Thermowells & Thermocouple Sheaths
- Employed as thermowells and thermocouple sheaths in high-temperature reactors and furnaces, where the combination of a melting point of 3,017 °C, dimensional accuracy, and resistance to aggressive process chemistry ensures reliable temperature measurement in the most demanding thermal and chemical service conditions.
- ✦ Semiconductor Reactive-Gas Delivery & Plasma Etching
- Used as flow liners in reactive-gas delivery systems and as structural components in plasma etching chamber assemblies, where Tantalum Tube's resistance to the halogen-based and highly oxidising process chemistries encountered in semiconductor manufacturing protects system integrity and prevents contamination of process streams.
- ✦ High-Vacuum Discharge & Shielding Components
- Applied as discharge and shielding components in high-vacuum systems, where low vapour pressure and vacuum stability ensure that tube components do not contribute to outgassing or vapour evolution that would contaminate the vacuum environment or degrade the performance of sensitive vacuum-based processes and instruments.
- ✦ Medical Implant Applications
- Used in medical implant applications where a hollow cylindrical geometry, biocompatibility, and resistance to body fluids are all required — supporting implant designs where the tube form provides structural function, fluid passage, or both within a physiological environment over extended service life.
