In the current era of technological acceleration, the demand for 99.99% Pure Copper (4N Grade) has transcended basic electrical wiring. It has become the foundational substrate for the global energy transition, semiconductor manufacturing, and aerospace engineering. As a premier manufacturer and exporter, we recognize that "purity" is not just a chemical metric—it is a performance guarantee for signal integrity, thermal dissipation, and structural reliability.
With an IACS (International Annealed Copper Standard) rating reaching up to 101%+, our 99.99% pure copper ensures minimal energy loss in high-voltage transmissions and precision electronics.
High purity eliminates internal stress points caused by oxygen or sulfur impurities, allowing for ultra-fine wire drawing (down to microns) without breakage.
Oxygen-Free High Conductivity (OFHC) copper prevents "hydrogen embrittlement," making it the ideal choice for vacuum environments and cryogenic applications.
The global shift toward Electric Vehicles (EVs) and Renewable Energy storage has tripled the demand for high-purity copper. Wind turbines and EV motors require the highest grade of copper wire to maximize efficiency and reduce heat buildup during high-current operation.
Artificial Intelligence necessitates massive data centers with advanced cooling systems. 99.99% pure copper busbars and heat sinks are critical for the thermal management systems that keep GPUs running at peak performance.
Recent geopolitical shifts have emphasized the need for reliable Exporters who can provide certified, high-grade materials with transparent ESG (Environmental, Social, and Governance) tracking.
Manufacturing 99.99% pure copper requires a rigorous multi-stage process that filters out metallic and non-metallic impurities at the molecular level.
Focus on high conductivity and high strength free cutting tellurium copper and other copper 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.
High-purity copper is utilized in MRI scanners and medical cabling for its bactericidal properties and high-fidelity signal transmission.
Critical for EV charging connectors and battery busbars, where high conductivity reduces charging time and heat loss.
Aerospace applications demand lightweight, high-performance wiring for generators and mission-critical communication equipment.
Corrosion-resistant copper alloys are essential for undersea cables and offshore sensor arrays, resisting bio-fouling and salt oxidation.
Our company has established its own independent R & D team, equipped with a complete production system and mature production technology.
Passed ISO9001:2015, ISO14001:2015 and OHSAS 45001:2018 certifications, reflecting global standards in quality and safety.
