This copper wire is a thin, flexible product with a typically round cross-section. Manufactured from pure copper (minimum 99.9% purity), it is designated as Cu-ETP, containing trace oxygen and produced through electrolytic refining. The material is highly workable, offers excellent electrical and thermal conductivity, and is also appreciated for its attractive appearance and easy care, making it a popular choice for decorative uses in homes. Due to its outstanding mechanical characteristics, bare copper wire is widely used across various applications.
Uncoated copper wire is simple to order from the Evek GmbH online shop. For any additional questions, our team is ready to provide expert advice.
Bare copper wire is highly elastic, easy to shape and polish, and remains ductile even at low temperatures. With no enamel coating, it delivers exceptional conductivity and low resistance, making it ideal for soft soldering.
Main applications for bare copper wire include:
- Hobby crafts and DIY projects
- Decorative purposes
- Windings and electrical conductors
- Contacts, terminals, and switches
Key advantages of bare copper wire:
- Excellent resistance to natural atmospheric conditions
