Wires for the highest requirements - manufactured with micrometer precision

High-end wire in the micro and sub-micrometer range

Our fine wires cover an exceptionally fine dimensional range - from Ø 0.020 mm to Ø 0.0005 mm. This allows us to exceed the limits of conventional drawing techniques.

ELSCHUKOM offers tailor-made fine wire strands and cables made from a variety of metallic and non-metallic materials

Fine wire strands consist of several individual wires that are either twisted together or around a core. Important parameters are:

• Pitch – affects the elasticity of the strand

• Lay direction – S-lay or Z-lay, also possible in combination

• Strand/rope diameter – defined by the circumscribing circle

Combining metals – wire solutions with added value For applications where different material properties need to be merged in a single wire – precisely manufactured and versatile

Special solutions for specific requirements

Material options:

• Sn (tin): 5–50% (shiny/matte)

• Ni (nickel): 5–10%

• Cu (copper): 5–25%

• Ag (silver): 1–50%

• Au / AuCo: 0.1–0.3 µm

Values refer to core wire diameter or mass percentage. Custom designs are provided.

ELSCHUKOM offers flat strips with widths of 1–90 mm and thicknesses of 0.10–0.50 mm, foils with thicknesses of 0.04–0.09 mm, profiled wires with special shapes such as: Trapezoid wire, Hexagonal wire, Square & triangular cross-section

Even the most complex geometries can be achieved using rolling or drawing technology and special profile drawing dies.

ELSCHUKOM composite wires consist of a core material (conductive or non-conductive) and one or multiple winding wires. These are wound in a spiral shape – with:

defined spacing (a > d), adjacent windings (a = d), overlapping windings (a < b) (b= width, flat wires only)

Also possible: alternating pitch for variable thermal or electrical properties.

Instead of a winding wire, a metal coated fiber can also be used if required - a non-conductive core with precise metallization.

Material diversity for demanding applications

Nickel-chromium alloys: High specific resistance, high tensile strength, low thermal conductivity

Copper-nickel alloys: Resistance adjustable with copper content, exceptional corrosion resistance

Iron-nickel alloys: High temperature coefficient, low linear expansion – ideally suited for high-precision applications

Various combinations for every challenge

Whether high-temperature resistant, electrically precise or mechanically durable - insulated wire compositions combine several materials to create a high-tech product. The insulation is precisely tailored to the application - from a thin layer of enamel to a thick plastic coating.

The ElCu family combines maximum tensile strength with excellent conductivity – for applications where both are critical. Depending on the requirements we select the optimal alloy:

ElCu99 – 99 % Cu, 1 % Ag, ElCu90 – 90 % Cu, 10 % Ag, ElCu50 / AgCu50 – 50 % Cu, 50 % Ag, ElCu28 / AgCu28 – 28 % Cu, 72 % Ag (eutectic)

ElCu combines the advantages of classic copper and silver alloys – with substantially higher tensile strength than pure copper or beryllium copper.

A patented wire solution developed by ELSCHUKOM based on a concentric combination of materials – ideal for complex applications with high-tech requirements.
