Ultra-fine wire options
Explore our comprehensive range of materials and wire forms to discover the ideal fit for your application.
Alleima manufactures fine medical wire in different product forms and these can be combined with a variety of surface finishes.
Single strand
Our single strand wire offers exceptional dimensional accuracy, surface quality, and material flexibility for advanced medical, electronic, and industrial applications. Available in a wide range of alloys and geometries, these wires can be tailored with coatings, finishes, and mechanical properties to meet your exact requirements.
Whether used as a stand-alone component or as part of an assembly, our single strand wire delivers the strength, conductivity, and reliability your designs demand.
| Parameter | Specification |  |
|---|---|---|
| Diameter range | 0.010 – 1 mm (0.00039 – 0.0394 in.) | |
| Wire profiles | Round, square, rectangular | |
| Surface finishes | Gold, nickel, silver plating; oxidized | |
| Coating options | Polymer coatings available | |

Ribbon wire
Alleima ribbon wire provides exceptional design flexibility and precise dimensional control for advanced medical, electronic, and industrial applications. With customizable aspect ratios and surface finishes, our ribbon wire is engineered to meet the stringent demands of miniaturized, flexible, and space-constrained devices.
Manufactured in a wide range of alloys and available with coatings or surface finishes, ribbon wire is ideal for applications requiring low-profile geometry, optimized winding behavior, or enhanced flexibility.
| Parameter | Specification |  |
|---|---|---|
| Thickness range | 0.013 – 0.75 mm (0.0005 – 0.03 in.) | |
| Aspect ratio | Up to 10:1 standard; higher available upon request | |
| Wire profiles | Flat / Ribbon (rectangular cross-section) | |
| Surface finishes | Gold, nickel, silver plating; oxidized | |
| Coating options | Polymer coatings available | |

Multi-filar cables
We offer multi-filar cables for advanced solutions for applications requiring multichannel signal, sensing, or power delivery in compact, flexible form factors. Individual single strand wires are precisely joined into multi-filar or micro-ribbon cable configurations, enabling streamlined assembly, optimized space utilization, and robust mechanical performance.
Multi-filar constructions allow for unmatched customization, including the ability to combine dissimilar alloys within a single cable, apply custom coatings, and optimize bonding characteristics for your device requirements.
| Parameter | Specification |  |
|---|---|---|
| Strand count | Custom, based on application requirements | |
| Strand profiles | Round, square, rectangular | |
| Alloy combinations | Mixed alloys supported within a single cable | |
| Coating options | Polyimide, polyester-imide, polyurethane, PTFE | |
| Bond strength | Adjustable to meet assembly and handling needs | |
| Length options | Continuous or selectively bonded lengths available | |
| Color coding | Industry standard or custom color coding available |
Cables
Alleima cable ables offer a highly flexible and customizable solution for advanced medical, electronic, and industrial applications. Formed by twisting or wrapping together multiple single strand or multi-filar wires, these cables deliver superior flexibility, mechanical durability, and design versatility.
Stranded cables provide a dynamic alternative to single-ended wires, allowing for deformation, independent strand movement, and incorporation of multiple alloy types within a single cable. They can be further enhanced with overall polymer or PTFE coatings to meet specific application requirements.
| Parameter | Specification |  |
|---|---|---|
| Cable diameter range | 0.018 mm – 0.25 mm (0.0007 – 0.010 in.) | |
| Cable construction | Twisted/wrapped single strand or multi-filar wires | |
| Strand coating options | Bare or individually coated strands | |
| Overall cable coating | Polymer or PTFE overcoating optional | |
| Alloy combinations | Mixed alloys supported within a single cable | |
| Cable flexibility | Highly flexible; suitable for dynamic assemblies |
Cored wire
Cored wires combine the best properties of multiple materials in a single wire design. Featuring a shell-and-core structure, cored wire enables enhanced electrical, mechanical, and radiographic performance tailored for advanced medical applications.
A typical cored configuration includes an Alleima® F562 (MP35N) shell paired with a conductive or radiopaque core material such as silver (Ag), platinum (Pt), gold (Au), or tantalum (Ta). This versatile structure allows for optimized electrical conductivity, radiopacity, fatigue resistance, and biocompatibility within a compact wire profile.
| Parameter | Specification |  |
|---|---|---|
| Diameter range | 0.020 mm – 3 mm (0.0008 – 0.118 in.) | |
| Shell materials | Alleima® F562 (MP35N), stainless steels (12R10, 316LVM) | |
| Core materials | Silver (Ag), platinum (Pt), gold (Au), tantalum (Ta), others | |
| Standard ccore dimension | 25% by area (custom core sizes available on request) | |
| OD tolerances | Size dependent but ranging from (± 0.0025 to ± 0.025 mm) | |
| Profile | Round |
Our wire offering includes an extensive range of stainless steels, precious metals and biocompatible alloys, such as cobalt-chromium (CoCr) alloys.
