Copper wire is a thin, flexible material, typically with a circular cross-section. Made from highly pure copper (minimum 99.9%), it is produced using electrolytic refining and is known as Cu-ETP copper. This material is easy to work with, offers outstanding electrical and thermal conductivity, and is also appreciated as a decorative element in homes due to its attractive look and low maintenance. Its excellent mechanical properties make bare copper wire a popular choice in various applications.
You can purchase uncoated copper wire conveniently from the Evek GmbH online store. If you have any questions, our team is ready to assist you.
Bare copper wire is elastic, easy to bend and polish, and remains ductile even at low temperatures. Without enamel coating, it maintains excellent electrical and thermal conductivity, features low resistance, and is ideal for soft soldering.
Main applications for bare copper wire include:
- Hobbies and crafts
- Decorative purposes
- Windings and electrical conductors
- Contacts, terminals, and switches
Key benefits of uncoated copper wire:
- Outstanding resistance in natural environments
- High flexibility
- Superior thermal and electrical conductivity
- Good formability and ease of processing
- Resistant to drinking and industrial water, aqueous and alkaline solutions, and non-oxidizing acids
- Long service life
Evek GmbH offers bare copper wire at competitive prices. As a reliable supplier, we can ship our semi-finished copper products worldwide with ease.
