Pure copper (C11000/C10100) boasts a conductivity of up to 101% IACS. This is the gold standard for power transmission, ensuring minimal energy loss in high-tension cables and EV charging stations.
With a thermal conductivity of approximately 390 W/(m·K), our pure copper materials are essential for heat sinks in 5G infrastructure and high-performance computing (HPC) cooling systems.
By engineering tellurium copper (C14500), we increase the machinability rating from 20% to 85% compared to pure copper, allowing for high-speed CNC production of intricate connector pins.
The global transition to Green Energy is the primary driver of the copper market today. We are seeing a massive pivot from standard electrolytic tough pitch (ETP) copper to Oxygen-Free High Conductivity (OFHC) Copper. This material is crucial for vacuum electronics and semiconductor manufacturing where hydrogen embrittlement must be avoided.
Global Procurement Trends: Enterprises in North America and the EU are increasingly seeking "Supply Chain Resilience." This means moving away from single-source risks and looking for Tier-1 suppliers in China who can offer both competitive pricing and "Industry 4.0" manufacturing standards.
Sichuan Kepai is at the forefront of China's industrial upgrade. Our factory integrates automated extrusion, cold drawing, and precision testing. This "Efficiency Advantage" allows us to provide wholesale pure copper properties that meet stringent aerospace and medical standards at a scale that local boutique suppliers cannot match.
Our Quality Management Systems (ISO9001:2015, IATF 16949) ensure that every batch of tellurium copper or beryllium bronze is traceable and consistent, providing the "Reliability" required by the Google E-E-A-T framework.
Copper is the circulatory system of the EV. From the battery busbars to the high-speed charging connectors, our C14500 tellurium copper ensures high current density with minimal heat buildup.
High-strength beryllium copper alloys (C17200) are utilized for bushings and landing gear components where extreme durability and non-sparking properties are non-negotiable.
Copper's inherent antimicrobial properties make it vital for hospital touch surfaces, while oxygen-free copper is used in MRI high-frequency shielding and precision surgical tools.
Equipped with a complete production system and mature technology, our team continuously develops new types of highly conductive oxygen-free tellurium copper.
Certified by ISO9001:2015, ISO14001:2015, and OHSAS 45001:2018. We meet global compliance requirements for quality and safety.
We focus on sustainable development through the use of environmentally friendly free-cutting copper alloys, reducing industrial environmental impact.
C11000 (ETP) contains a small amount of oxygen which is suitable for most electrical applications. C10100 (OFE) is 99.99% pure with almost zero oxygen, making it the choice for vacuum electronics where high-purity and resistance to hydrogen embrittlement are required.
Standard pure copper is "gummy" during machining, leading to tool wear and poor surface finish. Tellurium Copper (C14500) adds a small amount of tellurium to create short chips, significantly increasing production speed and part precision while maintaining 90%+ conductivity.
Yes. As a high-tech enterprise with 30+ patents, we work with engineers to develop specific copper-nickel-beryllium or sulfur-copper alloys tailored to specific tensile strength or conductivity requirements.
Every shipment undergoes spectral analysis, conductivity testing, and mechanical property verification. We provide MTC (Material Test Certificates) with every wholesale order to ensure full traceability.
