Engineered for excellence, certified for global industrial standards.
In the current era of Global Electrification and the Green Energy Revolution, the demand for 100% pure copper sheets has transcended traditional industrial uses. As a primary "Custom 100 Pure Copper Sheet Manufacturer," Sichuan Kepai New Materials is positioned at the intersection of material science and environmental sustainability. Pure copper (C11000/C10100) is the "nervous system" of modern infrastructure, providing unmatched electrical and thermal conductivity essential for decarbonization efforts worldwide.
High-purity copper is the backbone of EV battery busbars, charging stations, and high-efficiency traction motors, reducing energy loss by up to 15% compared to lower-grade alloys.
In photovoltaic (PV) systems and wind turbines, copper sheets provide the durable grounding and power distribution needed to handle fluctuating high-voltage loads.
The modernization of aging power grids into "Smart Grids" requires massive quantities of high-conductivity sheets for transformers and switchgear to minimize global carbon footprints.
Established in May 2017, Sichuan Kepai New Materials Co., Ltd. is a high-tech private enterprise specializing in the R&D, production, and global sale of high-conductivity, high-strength free-cutting tellurium copper and special copper alloys. Our facility spans over 29,000 square meters of state-of-the-art manufacturing space.
