In the era of rapid technological electrification, Oxygen-Free Copper (OFC) has become the backbone of modern power transmission and thermal management. Global supply chains are witnessing a shift where quality-driven procurement is prioritizing high-purity, oxygen-free materials (typically >99.99% Cu) to mitigate conductivity losses and enhance durability in demanding environments.
China's manufacturing ecosystem, specifically facilities like Sichuan Kepai, has transitioned from mass production to precision engineering. By leveraging vertical integration—from raw material smelting to final extrusion—Chinese factories now offer shorter lead times and superior cost-to-performance ratios for custom copper components.
Procurement teams are increasingly focused on supply chain resilience and ESG (Environmental, Social, and Governance) compliance. Sourcing from certified manufacturers ensures traceability, consistency in metallurgical properties, and adherence to international ASTM/DIN standards.
Whether in Electric Vehicle (EV) relays, 5G high-frequency transmission, or advanced medical robotics, OFC bars are the critical component. The requirement for precision, low-oxygen levels, and consistent grain size is non-negotiable for high-end OEMs.
Established in 2017, Sichuan Kepai represents the nexus of R&D and industrial manufacturing. Our commitment to high-conductivity, easy-to-machine alloys is driven by deep technical expertise.
Our team, composed of senior industry experts, focuses on continuous R&D. By exploring the boundaries of material science, we produce copper alloys that set the standard for conductivity and machinability.
We serve diverse sectors: New Energy Vehicles (NEV), Laser Cutting, Lithium Battery Relays, and Precision Electronics. Our product system is designed to reduce your production costs without compromising performance.
We are rooted in Sichuan but radiate globally. Our strategic logistics and established relationships with international enterprises ensure that our materials reach your factory floor on time, every time.
OFC is processed in a reducing atmosphere to remove oxygen, keeping oxygen levels below 0.001%. This eliminates hydrogen embrittlement and increases electrical conductivity to 101% IACS or higher, making it superior for critical electrical applications.
At Kepai, we utilize advanced equipment including eddy current conductance instruments and chemical composition labs to test every batch. All materials meet stringent international standards before shipping.
China offers a matured metallurgical supply chain. Factories like Kepai integrate R&D, smelting, and processing in one location, allowing for rapid prototyping, lower operational costs, and high-quality customized alloy solutions.
Established in 2017, our factory spans 9,000 sqm dedicated to innovative copper alloy production. From high-conductivity oxygen-free copper to specialized tellurium copper, we are a high-tech enterprise focused on the "13th Five-Year Plan" strategic materials.
Located in Sichuan Guanghan Industrial Development Zone, we combine geographical logistics advantages with a culture of innovation to ensure sustainable growth and industrial upgrading.
We operate a full suite of state-of-the-art machinery: from smelting and extrusion to drawing and straightening. Our lab includes metallographic polishing and servo universal testing machines to guarantee structural integrity.
Looking ahead, Sichuan Kepai New Materials Co., Ltd. is ready to be your partner in industrial excellence. Contact us to discuss your custom material requirements.
