Millberry Copper:

Definition and Composition

Millberry Copper refers to a specific grade of copper that is widely used in electrical, automotive, and industrial applications. It is renowned for its high purity and excellent conductivity. Millberry Copper is typically 99.9% pure and consists of uncoated, untinned, and unalloyed copper wire. Its smooth surface and absence of impurities make it ideal for various purposes.

Production Process

The production process of Millberry Copper involves several steps to ensure its high purity and quality. It begins with the collection of copper wire scrap, which undergoes a thorough cleaning process to remove any impurities or foreign materials. The cleaned scrap is then subjected to a mechanical shredding process, resulting in smaller pieces of copper wire. These tiny fragments are further processed using a granulation machine, transforming them into the fine copper granules that form the basis of Millberry Copper.


Millberry Copper finds extensive use in different industries due to its exceptional electrical conductivity and purity. Some common applications include:

  • Electrical Wiring: Millberry Copper’s high conductivity makes it an ideal choice for electrical wiring in homes, commercial buildings, and industrial settings.
