In the realm of electrical engineering, material purity defines performance. C11000 (ETP - Electrolytic Tough Pitch) Copper is the global standard for high-conductivity applications. With a minimum purity of 99.9%, it offers an electrical conductivity rating of 100% IACS (International Annealed Copper Standard). As leading China Soft Annealed Copper Strand C11000 Manufacturers, we utilize advanced electrolytic refining to ensure every strand meets stringent international specifications.
Why "Soft Annealed"? The annealing process involves heating the copper to a specific temperature and cooling it slowly to relieve internal stresses. This transforms rigid copper into a highly flexible, bend-resistant material. For industrial applications involving vibration or frequent movement, such as switchgears or automotive wiring, soft annealed copper strands prevent work hardening and mechanical failure, ensuring a long service life.
The global demand for high-quality copper strands is surging, driven by the green energy transition and the "Electrification of Everything." From the hyper-scale data centers in North America to the renewable energy grids in Europe, C11000 copper strands are the vital veins of modern infrastructure. As a premier supplier from China, we bridge the gap between high-volume manufacturing and precision engineering requirements.
Established in 2019 and headquartered in Liushi, the Capital of Electrical Appliances in China, Zhejiang Xingma Copper Industry Co., Ltd. has rapidly emerged as a cornerstone of the metal processing industry. Our facility spans over 10,000 square meters of construction area, housing over 100 dedicated professionals and a massive fleet of precision machinery.
Our core expertise lies in the mass production of mechanical automation components, ranging from soft copper stranded wires to complex metal stamping parts. We are committed to the construction of a modern enterprise mechanism, ensuring that every meter of wire leaving our factory meets the highest quality standards trusted by customers globally.
The shift toward solar and wind energy requires massive amounts of flexible grounding and connection components. Procurement managers are increasingly seeking durable, high-purity C11000 strands that can withstand outdoor environmental stressors while maintaining peak conductivity.
The automotive industry’s transition to EVs has created a specialized need for flexible battery connectors and high-current busbars. Soft annealed copper is preferred for its ability to handle the thermal expansion and vibration inherent in vehicle chassis design.
Modern smart grids require components that offer low impedance and high reliability. Our copper stranded wires are engineered to minimize energy loss, making them a preferred choice for state-of-the-art electrical distribution networks.
Where our high-performance copper products excel
Used in wiring harnesses and battery connections where vibration resistance is paramount.
Ensuring stable signal transmission and power supply in high-density telecom towers.
Providing soft connections for high-voltage breakers and industrial switches.
Critical for solar inverter connections and wind turbine grounding systems.
Located in Liushi, we are at the heart of the world's most advanced electrical material ecosystem. This proximity allows us to source raw electrolytic copper efficiently and pass the cost savings to our international clients.
Our workshop is equipped with over 300 high-end machines, including Dingtian wire drawing machines, Fuchuan beam machines, and high-precision annealing furnaces. This level of automation ensures consistency in every batch.
As a trusted export partner, our products are widely distributed across the Middle East, Europe, and the Americas. We understand international standards and compliance requirements like ISO9001 and ISO14001.
Our manufacturing process for Soft Annealed Copper Strand C11000 is a testament to our engineering rigor. It starts with the selection of premium electrolytic copper cathodes. The copper is drawn into fine filaments, often as thin as 0.05mm, depending on the required flexibility.
These filaments are then precision-twisted using planetary or tubular twisting machines to ensure uniform tension and diameter. The final annealing stage is critical; we use atmosphere-controlled furnaces to prevent oxidation, resulting in a bright, clean finish and the exact mechanical "softness" required for industrial applications.
