Precision manufacturing capabilities include OD tolerances as tight as ±0.003 mm, wall thickness tolerances as tight as ±0.005 mm, and length tolerances as tight as ±0.05 mm, depending on dimensions and manufacturing requirements.
Pure tantalum and tantalum-alloy grades are available, including R05200, R05400, Ta-2.5W, Ta-10W, and Ta-40Nb. Custom dimensions, tolerances, lengths, and material requirements can be reviewed according to customer specifications and technical drawings.


For larger Tantalum tubing, please check tantalum & tantalum alloy tubes.
Tantalum Capillary/Micro Tube (Ta Capillary/Micro Tube) belongs to the tantalum products range and is selected for corrosion resistance, biocompatibility and high-temperature stability. It is commonly used in sleeves, insulation tubes, protection tubes, furnace parts and flow or containment components as well as chemical processing, medical devices, electronics, vacuum systems and high-temperature components. When requesting a quote, confirm outside diameter, inside diameter, wall thickness, length, tolerance and end design.

R05200 is an unalloyed tantalum grade suitable for precision tubing applications requiring tantalum's characteristic corrosion resistance, ductility, high-temperature stability, and specialized material properties.
R05400 is another unalloyed tantalum grade available for applications requiring high-purity tantalum capillary and micro tubing.
Tantalum containing approximately 2.5% tungsten provides increased strength compared with unalloyed tantalum while retaining many of tantalum's useful corrosion and high-temperature characteristics.
Ta-10W provides higher strength than pure tantalum and is available for demanding applications requiring tantalum-tungsten alloy tubing.
Ta-40Nb combines tantalum and niobium and is available for specialized applications requiring a tantalum-niobium alloy.
Small-diameter tantalum tubing can be used as filament lead tubing and in cathode-insulator assemblies in X-ray equipment where compact geometry and tantalum material properties are required.
Precision tantalum tubing can be used to manufacture tantalum marker bands and other specialized medical components. For medical applications, the required material specification, dimensions, surface condition, cleanliness, and documentation should be specified with the inquiry.
Tantalum micro tubes can be used as small thermocouple protection or shielding tubes for selected high-temperature and specialized environments.
Tantalum capillary tubing is suitable for precision components used in electronic, vacuum, laboratory, and specialized instrumentation applications.
The refractory characteristics of tantalum make small-diameter tantalum tubing useful for selected furnace, thermal, and high-temperature components.
Custom tantalum micro tubing is also used in laboratories, research equipment, precision instruments, and specialized engineering assemblies.
Heeger Materials can review custom tantalum capillary and micro-tube requirements according to customer drawings and specifications.
Customization options include:
The Tantalum capillaries will be carefully placed in wooden cases or cartons with additional support from soft materials to prevent any shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
