High-purity metallurgy engineered to meet the structural, thermal, and electrical performance standards required by Nordic industrial enterprises.
Sweden is globally recognized as a frontrunner in green industrial transformation. Under its legislative goal of achieving zero net greenhouse gas emissions by 2045, the nation is systematically restructuring its transport, energy, and heavy industries. Core initiatives such as fossil-free steel production, rapid scaling of EV battery gigafactories (such as Northvolt), electrification of heavy-duty transport (led by Volvo and Scania), and the expansion of smart offshore electrical grids in the Baltic Sea demand a reliable, premium-grade supply of raw copper materials.
High-conductivity copper and specialized alloys are critical components in these green ecosystems. For instance, high-power charging (HPC) networks operating throughout Sweden require high-purity, oxygen-free copper (OFC) to minimize resistive losses and handle extreme currents without thermal runaway. Furthermore, Sweden’s telecommunication leader Ericsson depends heavily on highly precise, low-signal loss copper components for its 5G networks deployed globally. As local European copper processing mills operate under capacity limits and soaring energy costs, procuring high-performance copper from leading Asian manufacturers has become a strategic necessity for Swedish OEMs.

Equipped with advanced metallurgical instruments and mechanical testing systems to ensure absolute compliance with global industrial quality frameworks.
Our facility operates under rigorous international quality management systems, assuring uniform material consistency and environmental safety.
Industrial procurement in the Nordic region demands precise planning, robust logistics, and strict commercial transparency. At Sichuan Kepai, we align our sales and shipping workflows to integrate smoothly into Swedish supply frameworks. Recognizing that commodity pricing fluctuations impact project viability, we offer transparent, London Metal Exchange (LME)-linked pricing options combined with strategic hedging contracts to minimize cost volatility for long-term projects.
Copper products are highly sensitive to moisture and oxidation. All copper rods, sheets, and components undergo vacuum sealing or heavy-duty wooden box packaging, preventing corrosion during maritime transit. We regularly ship via major Chinese export hubs directly to key Swedish ports like Gothenburg and Stockholm. Our logistics team handles all customs documentation, material test reports (MTRs), and export declarations, ensuring clean arrival without delivery delays.
To accommodate large-scale infrastructure and manufacturing operations, we provide custom supply contracts that lock in copper prices based on real-time LME indexes. This price protection minimizes unexpected cost variations, allowing Swedish procurement managers to finalize long-term budgets with confidence.

The global copper sector is undergoing a major evolution, driven by the demands of next-generation applications. For decades, simple copper electrical wiring was sufficient. Today, however, high-frequency components, specialized laser optics, and rapid thermal cycling systems demand custom materials with tailored mechanical and physical properties. This shift has elevated the importance of alloys with high electrical conductivity, excellent wear resistance, and superior machinability.
One major trend is the replacement of leaded copper alloys with eco-friendly alternatives. Due to strict European environmental regulations, including RoHS directives, manufacturers are switching to lead-free free-cutting alloys. Tellurium copper (C14500) and sulfur copper (C14700) serve as excellent replacements. By introducing tellurium or sulfur into the copper matrix, these alloys achieve a machinability rating of 85% relative to free-cutting brass, while retaining over 90% IACS electrical conductivity. This unique combination allows precision CNC machining workshops to operate at high feed rates with minimal tool wear, reducing the cost per part for complex terminals, connectors, and nozzles.
Another major development is the growing demand for oxygen-free high-conductivity (OFHC) copper in high-vacuum environments and cryogenic systems. Traditional tough-pitch copper containing trace oxygen can suffer from hydrogen embrittlement when exposed to reducing gases at elevated temperatures. Oxygen-free coppers like C10100 prevent this failure mechanism, making them the standard choice for superconducting magnets, semiconductor processing chambers, and medical systems.
Expert answers to technical and logistical questions commonly raised by Swedish procurement officers and engineers.
Pure copper (like C11000) is highly conductive but extremely difficult to machine due to its ductility, which causes long, continuous chips that clog high-speed CNC machinery. Tellurium copper (C14500) includes a small amount of tellurium, creating short, brittle chips that significantly improve machinability (85% vs. 20% for pure copper). Despite this addition, it retains 93% IACS electrical conductivity and excellent thermal performance, making it the ideal material for high-precision EV charging contact pins that require rapid automated turning and low electrical resistance.
All materials manufactured at our plant undergo strict chemical composition testing. We utilize high-precision testing rooms and optical emission spectrometers to guarantee that hazardous substances, particularly lead content, remain strictly within the limits prescribed by the EU RoHS and REACH directives. We provide a full Mill Test Certificate (MTC) and Third-Party Compliance certificates with every export shipment to Sweden.
Our typical production lead time ranges from 15 to 30 days, depending on alloy complexity and quantity. Marine shipping from Chinese ports (such as Shanghai or Shenzhen) to the Port of Gothenburg generally takes between 35 and 45 days. For high-priority R&D projects or urgent factory components, we arrange air freight to Stockholm Arlanda Airport, reducing transit time to 5–7 business days.
Yes, we provide extensive custom extrusion services. Swedish engineers can submit CAD drawings (.dwg, .dxf, or step files) directly to our R&D team. We will manufacture custom tooling dies to produce specialized shapes, including hollow profiles, multi-channel bars, and asymmetrical copper segments, reducing the need for post-machining work at your facility.
Copper reacts with moisture and oxygen in the air, creating a green or dark patina. To prevent this, all of our products undergo an anti-tarnish treatment, followed by wrapping in moisture-barrier paper. The products are then sealed in heavy plastic bags with desiccants before being crated in export-grade, IPPC-certified wooden cases. This packaging ensures your copper arrives at your Swedish facility bright and oxidation-free.
Sichuan Kepai New Materials Co., Ltd. will continue to uphold its original intention, with even greater enthusiasm and determination, to engage in research and application in the field of new materials, contributing to the development of the new copper alloy materials industry in China and globally. We look forward to working hand in hand with friends from all walks of life to create a brilliant future together!
