From fine wires to fine tubes
Our long experience in the production of wires allows us an upstanding fine tube manufacturing. In addition to various stainless steels, which are principally used in medical applications, we can process other materials, such as tubes of precious metal alloys likes gold and platinum and non-ferrous metals such as brass, nickel, nickel silver, copper, and copper alloys.
Ultra-fine tube sizes
- Diameter outer:0.25 - 4 mm (0.00984″ - 0.157″)
- Diameter inner: 0.05 - 2.9 mm (0.00197″ - 0.114″)
- Wall thickness:/ 0.04 – 1.0 mm (0.00157” - 0.04″)
Alleima supplies high-quality precision tubes in both seamless and welded forms, with dimensional accuracy up to ±0.001 mm. Tubes are available straightened to defined lengths or supplied in coils, meeting both international standards and specific customer requirements.
Electroplating
We offer advanced electroplating for tubes, applying the same high-performance metallic coatings used on our wires. Options include gold, nickel, platinum, silver, tungsten, and more—delivering enhanced acid resistance, biocompatibility, or tailored electrical properties. Our reel-to-reel electroplating process ensures continuous, homogeneous coatings free from porosity or cracks. Contact us to learn more.
Plastic Insulation
For probes, catheters, and similar applications, we provide a range of plastic and biocompatible insulation options. Our multi-layer coating process guarantees 100% coverage, eliminating the risk of pinholes and ensuring reliable protection for fine tubes in demanding medical environments.

Multi-lumen tubes
Certain medical applications require tubes with two or more separate chambers. Alleima has developed specialized processes to meet the stringent demands of multi-lumen tube manufacturing, enabling precise integration of dual or triple chambers within a single tube. Inner conductors can be installed either solid or loose, depending on your application requirements.
By combining advanced electroplating and polymeric coating technologies, we are able to deliver highly complex and sophisticated tube solutions tailored to your needs. For more information about our multi-lumen capabilities, please contact your technical sales team.
Medical tubes in larger dimensions
Alleima also offers precision medical tubes in larger stainless steel dimensions, supporting a wide range of orthopedic, cardiovascular, and diagnostic applications. Our in-house production enables tailor-made sizes—even in small batches—ensuring you receive the exact dimensions and performance your application demands.
Size range
- Outside diameter: 0.5-25.4 mm (0.01971"-1.000")
- Wall thickness: 0.1-8 mm (0.0039"-0.315")
