Galvorn® C – Carbon Nanotube Twisted Conductive Yarn
Starting at $126 ($25.20 / m)
Galvorn® C Twisted Yarn is a specialized version of our carbon nanotube (CNT) yarn, engineered specifically for applications that need a lightweight conductor, but do not want the full strength of Galvorn® HS. Sometimes less is more.
Galvorn C has about 75% the conductivity and 40% of the strength of Galvorn HS. For advanced textile applications, Galvorn C offers a significantly superior, lightweight alternative to traditional conductive threads like stainless steel and silver-coated nylon. For some signal wire applications, it can meet the basic conductivity requirements, while still being stronger, more flexible, more durable, and corrosion resistant compared to copper.
Key Benefits
- Optimized for Textile Applications: Superior electrical performance compared to traditional conductive yarns. Engineered for easier knitting, weaving, embroidery, and sewing on commercial equipment.
- Lightweight & Stronger: Up to 80% lighter and 2x stronger than stainless steel thread.
- Corrosion-Proof & Chemically Stable: It will not rust, pit, or oxidize.
- Cost-Effective: ~ 80% less expensive than our ultra-high-strength Galvorn HS grade.
- Bio-Compatible: Safe for skin contact and 100% recyclable.
- Sustainable at Scale: Production at scale is less energy intensive than metals.
- Recyclable: Can be recycled from mixed streams over and over without losing properties.
- Made in the USA: Produced at our headquarters in Houston, Texas.

Sustainable Production at Scale
Highest Performing CNT Products
"We have tested different CNT yarns and in terms of mechanical properties allowing it to withstand mechanical automation, yours are the best. The multifunctionality is key. We can monitor strength, temperature, curing and strength, and can apply heat. With one material you can do many things, this is very attractive to many companies."
A Research Institution for Aerospace
“It’s amazing. No other material can do what this material does!”
A Major Global Aerospace Company
"Many of our customers were attracted not only to the thermoelectric technology, but also to Galvorn’s unique combination of high-performance properties. We are optimistic about the road ahead with Galvorn, in this first thermoelectric application, but also beyond it. We see the broad market need for a high-performance material like Galvorn that is also good for the environment.”
Hiroki Iijima, Sales Manager at Tokai Rika
"We were able to create a miniaturized, minimally-invasive neuromodulation technology enabled by the high efficiency of charge transfer and high conductivity of Galvorn. Our design makes these types therapies far more accessible for patients living with conditions like epilepsy, depression, and chronic pain."
