Pioneering High-Conductivity Copper Alloy Innovation since 2017.
Established in May 2017, Kepai is a high-tech private enterprise specializing in the R&D, production, and sales of high-conductivity, high-strength free-cutting tellurium copper and other special copper alloys. Our mission is to bridge the gap between material science and high-end industrial application through precision engineering.
State-of-the-art factory floor space dedicated to high-purity copper production.
Continuous innovation in tellurium and beryllium copper alloy formulations.
In the current global industrial landscape, terminal copper tape is no longer a simple commodity. It is the "nervous system" of modern electrical infrastructure. From the micro-connectors in smartphones to the heavy-duty busbars in Electric Vehicle (EV) battery packs, the demand for high-performance copper alloys is surging. As an OEM terminal copper tape manufacturer, Kepai New Materials understands that the industry is shifting from standard C11000 grade copper toward specialized alloys that can withstand higher temperatures, offer better machinability, and maintain superior conductivity.
The global market for copper strips and tapes is projected to grow significantly, driven by the decarbonization of energy grids and the rapid expansion of AI data centers, both of which require massive amounts of high-efficiency conductive materials.
While traditional pure copper offers excellent conductivity, it often fails in high-precision automated manufacturing due to its softness and poor "chip-breaking" properties during high-speed stamping. Our technical roadmap focuses on the "Golden Triangle" of metallurgy: Conductivity, Strength, and Machinability.
Why source from China? The answer lies in ecosystem integration. Sichuan Kepai New Materials leverages China's complete industrial chain—from raw material mining and smelting to precision slitting and global logistics.
Our facility in Sichuan benefits from stable energy costs and a direct link to high-purity copper sources. This geographical advantage, combined with our 29,000 m² integrated production line, allows us to reduce lead times by 30% compared to Western counterparts. We don't just export products; we export supply chain stability. In a world of volatile copper prices, our efficient production minimizes waste, passing the cost savings directly to our OEM partners.
Terminal copper tape is the foundational material for several critical sectors:
High-current charging guns require C14500 copper tape for contacts to prevent overheating and ensure a lifetime of 10,000+ plug cycles.
Miniaturized connectors in server racks demand ultra-thin C51100 phosphor bronze tape with high elasticity and corrosion resistance.
Photovoltaic inverters rely on our oxygen-free copper tapes for long-term durability in harsh outdoor environments.
The future of terminal copper tape lies in surface engineering and ultra-precision slitting. As components get smaller, the surface roughness and edge burrs of the tape become critical. Kepai is currently investing in AI-driven quality inspection systems that detect microscopic defects at 500 meters per minute. Furthermore, the industry is moving toward "sustainable copper"—incorporating recycled high-purity scrap without compromising the IACS ratings, a move Kepai is pioneering through our environmentally friendly production protocols.
Trust is built on certification. Our manufacturing processes are strictly aligned with international standards:
• IATF 16949: The gold standard for automotive supply chains.
• ISO 9001 & 14001: Ensuring quality management and environmental stewardship.
• RoHS & REACH: Guaranteeing our materials are free from hazardous substances, essential for global market entry.
