This copper wire is thin, long, and highly flexible, typically featuring a round cross-section. Manufactured from pure copper (minimum 99.9%) under the designation Cu-ETP, it contains residual oxygen and is produced by electrolytic refining. The material is easy to work with, offers excellent electrical and thermal conductivity, and is popular for decorative uses in homes thanks to its attractive look and low maintenance. Its outstanding mechanical properties make bare copper wire a versatile product for many applications.
You can easily purchase uncoated copper wire in the Evek GmbH online shop. If you have any questions, our team is available to assist you.
Bare copper wire is highly flexible, easy to shape and polish, and remains tough even at low temperatures. Without enamel coating, it provides excellent conductivity for electricity and heat, has low resistance, and is ideal for soft soldering tasks.
Main applications for bare copper wire include:
- Hobbies and crafts
- Decorative purposes
- Windings and electrical conductors
- Contacts, terminals, and switches
Advantages of bare copper wire include:
