Advanced materials customized to exceed the manufacturing standards of Eastern European industrial sectors.
Bulgaria's positioning as a primary logistics and manufacturing gateway in Southeastern Europe has driven unprecedented structural demand for advanced engineering components. Undergoing a robust wave of industrial modernization, the country has become a strategic hub for automotive sub-assemblies, electronic components, precision mechanical engineering, and high-voltage power distribution networks.
Key economic zones such as the Trakia Economic Zone (TEZ) in Plovdiv and the industrial parks around Sofia require a constant, stable, and certified supply of high-purity copper and specialized copper alloys. The automotive industry in Bulgaria, which contributes significantly to the GDP, relies heavily on high-performance copper for sensor systems, micro-connectors, wiring harnesses, and EV (electric vehicle) charging infrastructures.
Additionally, Bulgaria's national commitments to the EU Green Deal are driving a systematic upgrade of its regional electrical grid. This modernization has significantly increased the demand for oxygen-free copper with high thermal and electrical conductivity (≥100% IACS), a key material for power transformer manufacturing, renewable energy systems integration, and precision plasma cutting electrodes.
In the global market, procurement departments for multinational corporations face mounting challenges related to raw material consistency, trace-element limitations, and compliance declarations. When importing pure copper and copper alloys into the European Union, standard quality targets are no longer sufficient. Industrial buyers look for reliable exporters that can supply chemical-grade verification sheets and metallographic certificates of compliance.
Sichuan Kepai New Material Co., Ltd. addresses these global demands by providing full supply chain transparency. From high-grade raw cathode copper melting to the final extrusion and drawing phases, our internal processing metrics ensure that trace elements are strictly regulated. This is particularly crucial for manufacturing oxygen-free tellurium copper, sulfur copper, and beryllium copper alloys where impurities can degrade electrical conductance or create micro-cracking during high-speed precision stamping.
| Alloy Grade | Copper Purity (%) | Electrical Conductivity (IACS) | Primary Industrial Applications |
|---|---|---|---|
| C10100 (OFC) | ≥ 99.99% | 101% | Semiconductors, vacuum electronics, high-voltage equipment |
| C11000 (ETP) | ≥ 99.90% | 100% | Busbars, architectural copper, standard electrical cables |
| C14500 (Te-Cu) | ≥ 99.00% | 85% - 98% | Plasma cutting nozzles, CNC turned parts, EV connector pins |
| C17200 (Be-Cu) | Base Copper | 22% - 30% | High-strength springs, non-sparking tools, aerospace actuators |
Providing high-conductivity oxygen-free copper plates, tubes, and custom profiles for EV relays, battery pack connectors, and ultra-fast charging gun terminals.
Delivering heavy-duty oxygen-free tellurium and high-purity copper bars for high-voltage power transmission panels and low-loss distribution substations.
Supplying free-machining C14500 tellurium copper rods to guarantee long nozzle lifespan and stable cutting speeds in fiber laser systems across Bulgaria.
Sichuan Kepai New Materials Co., Ltd., established in 2017, is a high-tech enterprise integrating research and development, production, and sales. Currently, the factory covers an area of approximately 9,000 square meters, with an office space of about 1,000 square meters. The company primarily engages in the production of strategic emerging new materials, including special copper alloys such as tellurium copper, high-conductivity oxygen-free copper, silver copper, and dispersion copper, while also focusing on the research and development of high-conductivity, easy-to-machine, high-strength copper alloys. The products are mainly applied in high-tech fields such as new energy vehicles, 5G technology, laser cutting, and lithium battery relays.
The company is located in the western area of the Sichuan Guanghan Industrial Development Zone, adjacent to National Highway 108, boasting a superior geographical location and convenient transportation, which lays a solid foundation for the rapid development of the enterprise. Since its establishment, Kepai has adhered to the business philosophy of "innovation-driven development, quality wins the market," committed to providing customers with the highest quality high-end copper alloy materials, and promoting industrial upgrading and sustainable development.
Technological innovation is the core competitiveness of Sichuan Kepai New Materials Co., Ltd. The company has a research and development and production team composed of senior industry experts who keep pace with international cutting-edge technology trends and continuously explore the unknown boundaries in the field of new copper alloy materials. Through a combination of independent research and development and industry-university-research collaboration, Kepai has made breakthrough progress in several areas, including high-performance tellurium copper, lead copper, and sulfur copper. Many of its technological achievements have reached international advanced levels and have been successfully applied in various industries such as new energy vehicles, precision machining parts, plasma cutting, relays, and energy storage, earning widespread recognition and praise in the market.
To guarantee structural reliability and consistent material properties, we operate an integrated downstream production framework.
Exclusively manufactured to meet specialized high-stress requirements in aviation, metallurgy, and automated production.
Entering the EU territory via Bulgarian custom entries—such as the Black Sea ports of Varna and Burgas, or cross-border inland corridors—requires meticulous documentation. Every single consignment shipped from Sichuan Kepai to Bulgaria is backed by comprehensive administrative paperwork to eliminate customs delays and keep your assembly operations running smoothly.
Industrial applications continue to push the boundaries of materials science. The demand for materials that combine high mechanical stability with electrical conductivity has led Sichuan Kepai to develop next-generation dispersion-strengthened copper and customized copper alloys.
Our metallurgy research roadmap is designed to solve common industrial trade-offs. Standard high-purity copper is highly conductive but difficult to machine. By introducing trace amounts of elements like tellurium or sulfur, we achieve high machinability without compromising the material's electrical performance. This ensures that manufacturers in Sofia and Plovdiv can produce intricate components with minimal tool wear and maximum efficiency.
