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″)
High-quality precision tubes can be seamless and welded. We supply both versions with an accuracy of up to + /-0.001mm, straightened in defined lengths or in coils. We follow international standards and customer requirements.
Electroplating
We can apply the same metallic coatings as on the wires. Again, we have the possibility to achieve acid resistance, biocompatibility, or to affect the electrical properties of the tubes. We can electroplate continuous tubes and wires (reel to reel). Our electroplating capabilities are highly efficient and can guarantee coatings to be homogeneous, without porosity (pinholes) or cracs. Metals: Gold, Nickel, Platinum, Silver, Tungsten and many others. Talk to your sales representative for more information.
Plastic Insulation
For probes or catheters, it is often important that they are coated with
plastics. We can apply different types of insulation or biocompatible materials on the fine tubes. With our multi-layer coating process, a 100% coverage is guaranteed. Pinholes can’t emerge with this technology.
Types of insulation
| Type of insulation | Temp | * |
| Polyurethan V130* | 130C° | L |
| Polyurethan V155* | 155C° | L |
| Polyesterimid W180* | 180C° | |
| Polyesterimid W200 | 200C° | |
| Polyimid C300 | 300C° | |
| Silicon | 200C° | |
| Adhesive varnish | ||
| Polyvynilbutyral | 100C° | L |
| Polyamid | 180C° | L |
| * available in various colours. L = Solderable |
Multi-lumen tubes
Some applications require that the tube has two or even three different chambers. For this exceptional part, we have developed a special process, that allows us to meet the high requirements of such a product. If desired, the inner conductor can be installed solid or loose in the tube.
With the combination of our electroplating and polymeric coating, Alleima has an excellent starting position to realize very complex and sophisticated products. If desired, the inner conductor can be installed solid or loose in the pipe.
Don’t hesitate to contact your local sales representative if you want to learn more about our multi-lumen tubes.
Medical tubes in larger dimensions
Alleima can also offer larger medical tube dimensions. Our portfolio of precision medical tubes in stainless steel in larger dimensions cover a wide range of orthopedic, cardiovascular, and diagnostic applications. Our in-house production of medical tubes allows for tailor-made sizes in small batches.
Size range
- Outside diameter: 0.5-25.4 mm (0.01971"-1.000")
- Wall thickness: 0.1-8 mm (0.0039"-0.315")
