ETP Copper Rod

ECOR specializes in the production of ETP (Electrolytic Tough Pitch) Copper Rod; at an industry standard 5/16″ and meeting ASTM International standards for manufacturers across North America. 

ETP Copper Rod is known for its high electrical conductivity, thermal performance, and excellent workability. It is renowned for its high conductivity—exceeding 100% IACS (International Annealed Copper Standard)—and is a foundational material used in a wide range of applications.

It is frequently sourced by OEMs for use in the electrification of the automobile industry and plays a vital role in modern infrastructure and technology. ETP Copper Rod is also an essential material for applications that demand superior electrical performance due to its unparalleled conductivity that ensures reliable energy transfer and minimal power loss, ranging from massive power grid systems to compact, high-efficiency electronics like smartphones.

ETP copper (C11000) contains a minimum of 99.9% pure copper and a small amount of oxygen (typically around 0.02-0.05%). This small oxygen content improves the copper’s conductivity and makes it well-suited for applications where high electrical efficiency is essential.

Beyond performance, ETP Copper Rod is valued for its scalability and sustainability. It is produced in large volumes to meet growing industrial demands, making it a cornerstone material for large-scale manufacturing and engineering. Additionally, the production of ETP copper is increasingly aligned with circular economy principles, supporting efforts to reduce environmental impact through recycling, and its sustainable sourcing aligns with the holistic Vision 2030 program that helps shape ECOR.

At ECOR, our facility has the experience and exacting quality standards to meet the requirements of the toughest electrical applications. Whether it’s powering homes, driving electric vehicles, or enabling the next wave of smart technologies, our copper rod is the essential first link in the chain of innovation.
