Top-tier sulfur copper and high-conductivity alloys tailored for German industrial standards (DIN).
Germany stands as the industrial heartbeat of Europe, characterized by its "Mittelstand" precision manufacturing and global leadership in automotive, electrical engineering, and chemical industries. In this high-stakes environment, the demand for C14700 Sulfur Copper has surged. As a material that offers a unique equilibrium between high electrical conductivity (min 90% IACS) and exceptional machinability, sulfur copper is the preferred choice for German CNC machining centers producing intricate components for EV charging infrastructure, sensor housings, and plasma cutting nozzles.
Unlike standard pure copper, which can be "gummy" and difficult to machine, the controlled addition of sulfur creates a "free-cutting" effect. For German enterprises focusing on Industry 4.0, this means higher spindle speeds, longer tool life, and significantly reduced production downtime.
C14700 provides the signal integrity required for high-frequency connectors used in Germany's nationwide 5G rollout and automation hubs.
With major German OEMs shifting to EV, our sulfur copper is vital for high-current terminals and heat-dissipating battery components.
Supports the tight tolerances (micrometer level) required by the German mechanical engineering sector (Maschinenbau).
Bridging the gap between high-volume production and German-level quality precision.

At Sichuan Kepai New Materials Co., Ltd., we understand that "Made in China" must now meet the rigorous demands of "German Engineering." Our competitive advantage lies in our vertically integrated supply chain and advanced smelting technology. By utilizing oxygen-free casting and precision drawing, we produce Sulfur Copper that exceeds ASTM B301 and DIN EN standards.
Efficiency Gain: Our factory leverages AI-driven quality control and automated extrusion lines, allowing us to offer a 20-30% cost-efficiency advantage over European domestic manufacturers without compromising the chemical purity or mechanical integrity of the alloys.
Established in May 2017, Sichuan Kepai New Materials Co., Ltd. is a high-tech private company specializing in R&D, production and sales of high conductivity and high strength free cutting tellurium copper and other special copper alloys.
Our facility spans 29,000 square meters and houses the industry's core technical personnel. We have passed ISO9001:2015, ISO14001:2015, and OHSAS 45001:2018, reflecting our international standards in quality, environment, and occupational health.
Semantic insights into material science trends for 2025 and beyond.
Global procurement is shifting toward "Clean Alloys." Our Sulfur Copper is RoHS and REACH compliant, ensuring zero lead-contamination issues for German exports.
As electronic devices shrink, the need for materials that can be machined into ultra-thin walls without breaking is critical. C14700 offers the grain structure needed for this.
With AI servers and high-power electronics generating more heat, the thermal conductivity of our alloys ensures reliable operation in demanding German data centers.
In addition to high share of the domestic copper alloy market, Kepai has exported to overseas clients with high reputation in Germany, Italy, and North America.
While both are free-cutting copper alloys, C14500 (Tellurium) generally offers slightly better conductivity and heat resistance, whereas C14700 (Sulfur) is more cost-effective for high-speed machining applications where conductivity above 90% IACS is sufficient.
Yes, all our exports to Germany comply with DIN standards and are RoHS/REACH certified. We provide 3.1 Material Certificates with every shipment to ensure full traceability.
Typically, production takes 15-20 days, and sea freight to major German ports takes 30-35 days. We also offer air freight for urgent R&D prototype requirements.
Absolutely. Our independent R&D team can adjust sulfur or other element concentrations to meet specific mechanical or electrical requirements provided by your engineering team.
