C11000, commonly known as Electrolytic Tough Pitch (ETP) copper, represents the industry standard for electrical conductivity and ductility. With a minimum copper content of 99.90%, it is the most widely used copper alloy in the world. As we navigate the complexities of modern manufacturing, understanding the capabilities of C11000 factories is vital for procurement and engineering teams.
Why choose C11000? It offers exceptional thermal and electrical conductivity, excellent corrosion resistance, and superior formability. It is the backbone of the renewable energy sector, automotive wiring harnesses, and power distribution infrastructure.
The global transition towards electrification—driven by EVs, data centers, and AI-driven hardware—has created an unprecedented demand for high-purity copper alloys. Key trends include:
Established in 2017, Sichuan Kepai has emerged as a high-tech cornerstone in the Chinese copper industry. Our 9,000 square meter facility acts as a hub for research, development, and high-volume production. We don't just supply metal; we provide material science solutions that empower the national strategic emerging industries, including 5G infrastructure and high-speed laser cutting technologies.
Kepai’s technical strength lies in our rigorous R&D methodology. We utilize advanced eddy current conductivity instruments and servohydraulic testing machines to ensure every batch meets international standards. Our process involves:
C11000 (ETP) contains trace amounts of oxygen, which makes it slightly easier to manufacture. Oxygen-Free Copper (OFC) is required for applications involving hydrogen environments to prevent hydrogen embrittlement.
Yes, we adhere to international standards and provide full chemical composition analysis, hardness test reports, and conductivity certificates for every shipment.
