An Industrial Deep-Dive into Conductivity, Machinability, and Global Supply Chain Dynamics
In the modern era of precision engineering, the demand for "High Purity" isn't just a quality preference—it's a fundamental requirement. Sichuan Kepai New Materials Co., Ltd. has stood at the forefront of this evolution since 2017. Traditional copper alloys often face a trade-off between electrical conductivity and mechanical machinability. However, our proprietary R&D in Oxygen-Free Tellurium Copper has effectively bridged this gap, offering a material that maintains >98% IACS conductivity while providing the free-cutting characteristics necessary for complex CNC operations.

Located in the heart of Sichuan’s industrial hub, our facility leverages the world-class supply chain integration unique to China. This allows us to provide OEM and ODM services with a speed-to-market that Western manufacturers struggle to match. By controlling the entire process from smelting to final extrusion, we ensure 100% traceability and purity standards that meet ASTM, DIN, and JIS specifications.
Our oxygen-free highly conductive tellurium copper alloy features independent intellectual property rights, specifically engineered for the high-end plasma cutting and NEV charging connector markets.
Fully compliant with ISO9001:2015, ISO14001:2015, and OHSAS 45001:2018. We provide RoHS and REACH certifications for all high-purity exports to ensure seamless global customs entry.
Green production is at our core. By utilizing eco-friendly free-cutting copper alloys, we reduce the environmental footprint while enhancing the longevity of end-user components.
For procurement directors at Fortune 500 aerospace or automotive firms, the pain point is often consistency. High-purity C10100 or C17200 Beryllium Copper must exhibit identical tensile strength and conductivity across every batch. Kepai addresses this through advanced spectral analysis and ultrasonic testing, ensuring that every kilometer of copper tube or foil delivered to overseas clients in the USA, Germany, or Japan meets the "Kepai Standard."
Where High Purity Meets Real-World Performance
High-conductivity tellurium copper is the gold standard for EV charging gun contacts, reducing heat generation and increasing charging efficiency by up to 15%.
C17200 Beryllium Copper provides the extreme fatigue resistance required for aircraft landing gear bushings and satellite connectors.
Oxygen-free copper tubes are vital for MRI cooling systems and antimicrobial surfaces in high-traffic hospital environments.
Our independent R&D team doesn't just manufacture; they innovate. From developing new precipitation-hardening cycles to perfecting sulfur-copper extrusion, we provide the technical information gain that gives our partners a competitive edge.
Automated manufacturing systems ensure tolerance levels within ±0.005mm.
Inductively Coupled Plasma (ICP) testing for absolute purity verification.
Tailored OEM molds for proprietary component designs.
Strategic export partnerships for DDP/CIF shipping worldwide.
Kepai specializes in "Oxygen-Free" Tellurium Copper. Unlike standard ETP-based tellurium copper, our oxygen-free version prevents hydrogen embrittlement and provides significantly better performance in vacuum and high-temperature brazing applications.
Yes. We offer 24/7 technical consultancy and have a dedicated export department that handles localized compliance, language support, and technical documentation required for European and North American markets.
While we are a large-scale factory with 29,000sqm of space, our R&D-focused structure allows us to support pilot runs and custom metallurgical prototyping for established industrial partners.
Standard stock items ship within 7 days. Custom OEM orders generally require 15-30 days, depending on the complexity of the alloy and required certifications.
