Lightweight signal wire and cable with Galvorn

Galvorn is the lighter, stronger, and more flexible alternative to copper, meeting the growing need for lightweight signal wires and cables across aerospace and automotive applications.

KEY BENEFITS

Lighter

80% less dense than copper

Galvorn signal wire and cable present significant lightweighting opportunities for the aerospace, defense, and automotive industries, which increasingly need more sensors and data transmission.

  • Galvorn’s density is 1.6 g/cm3
  • Copper’s density is 9.0 g/cm3
  • Aluminum’s density is 2.7 g/cm3

Stronger

50x stronger than copper

Galvorn is 50 times stronger than copper and 15 times stronger than steel on a per mass basis. This strength can greatly improve efficiency in manufacturing, distribution, and installation. It is especially useful in extreme environments because of its amazing durability.

More flexible

100x flex life of copper

Galvorn wiring is not only strong, but highly flexible. Unlike copper, it is great for applications that need bending and flexing. This includes robotics, wearable electronics, and medical implants. Even phone charging cables, which are constantly wound and unwound.

Galvorn is an excellent alternative to copper

Galvorn's electrical conductivity is nearly equivalent to copper on a per mass basis: 6150 Sm2/kg for Galvorn vs. 6300 Sm2/kg for copper. Signal wire and cable are applications where the full conductivity of copper is not required, and where less mass can make a big difference.

Formula 1 racing with Galvorn signal wire copy

For example, in working with a potential strategic partner in Formula 1 racing, we demonstrated that replacing 28 AWG copper signal wire with Galvorn wire reduces weight by ~70 grams per 100 m of wire. Considering that signal wire makes up an estimated 50-60% of aircraft wiring and 60-70% of modern vehicle wiring, that kind of weight savings adds up.

Superior Bend Radius for Tighter Spaces

Galvorn can be bent into a very small radius without damage; for example, Galvorn fibers can even be tied into a tight knot (try that with copper!). What does this mean for applications? Galvorn wiring solutions can be installed in much tighter spaces, making more efficient use of space overall.

Superior Heat Dissipation

Galvorn conducts heat well with a thermal conductivity of 450 W/m-K. For comparison, copper’s thermal conductivity is 385 W/m-K. Higher thermal conductivity makes it better at dissipating heat, carrying more current on a per mass basis. Some applications need their conductive wire to handle higher current.

Corrosion & Oxidation Resistance

Galvorn, unlike copper, does not corrode or oxidize over time; it will not rust or pit, even after years of use. This makes it suitable for use in harsh environments. Galvorn is carbon, and the carbon-carbon bonds in carbon nanomaterials are similar to those found in graphite or diamond. These bonds resist oxidation and chemical reactions under standard conditions (e.g., air, water, or mild acids), making it inherently stable.

Galvorn Carbon Nanotube AUX Cable

In this video, we demonstrate an auxiliary cable made with Galvorn carbon nanotube (CNT) conductors and shielding. The cable has two CNT yarn conductors that are insulated with a nylon braid and then shielded with a CNT fiber braid. The sound quality is great and this audio cable application highlights the tremendous potential for Galvorn in signal wire and cables more broadly.
