Our Advantages in Processing Barra Redonda de Cobre 110

Superior Electrical Conductivity
The manufacturing process ensures 99.9% pure copper content, resulting in exceptional electrical conductivity properties. This high purity level is maintained through careful material selection and quality control during the bar forming process.
Precise Round Bar Formation
Advanced continuous casting and drawing techniques create perfectly cylindrical bars with tight dimensional tolerances. This precision manufacturing ensures consistent diameter and surface finish across the entire length of the bar.


Enhanced Machinability Properties
The controlled cooling process during manufacturing results in optimal grain structure, providing excellent machinability characteristics. This allows for precise cutting, threading, and forming operations without compromising material integrity.
