In the landscape of Industry 4.0, the demand for materials with excellent thermal and electrical conductivity has transcended traditional boundaries. From the rapid expansion of the New Energy Vehicle (NEV) market to the intricate requirements of 5G telecommunications and aerospace engineering, copper alloys serve as the nervous system of modern technology. As a premier manufacturer and exporter, we focus on providing "Information Gain"—technical advantages that go beyond standard market offerings.
High-conductivity alloys, such as Tellurium Copper (C14500) and Beryllium Copper (C17200), are no longer just commodities; they are engineered solutions. These materials must maintain structural integrity under high heat, resist corrosion in marine environments, and ensure zero-loss signal transmission in medical devices.
Our OFT (Oxygen-Free Tellurium) copper achieves over 93% IACS conductivity, significantly reducing energy waste in high-voltage charging systems.
High-purity alloys ensure rapid heat dissipation, preventing processor throttling in AI computing centers and aerospace avionics.
The addition of tellurium or sulfur creates "free-cutting" properties, allowing for precision manufacturing of complex micro-connectors with minimal tool wear.
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 company has passed ISO9001:2015, ISO14001:2015, and OHSAS 45001:2018. We participate in the formulation of industry standards, enhancing market influence through technological innovation.
The global copper alloy market is shifting towards "Multi-Property Harmonization." Users no longer choose between strength and conductivity; they demand both. Key trends include:
Electronic components are shrinking, requiring copper foils like C17200 Beryllium Bronze that offer extreme strength in ultra-thin dimensions.
A move toward lead-free or low-lead alternatives (like Sulfur Copper C14700) to meet RoHS and REACH compliance in European and North American markets.
The 6G and satellite internet era requires oxygen-free high conductivity (OFHC) materials to minimize skin effect losses at gigahertz frequencies.
China has evolved from a volume producer to a global R&D hub for advanced materials. Kepai’s manufacturing facility in Sichuan represents the pinnacle of this evolution:
High-purity copper's antibacterial properties and conductivity make it ideal for MRI components, surgical robotic arms, and diagnostic imaging sensors.
Tellurium copper is the preferred material for EV charging gun pins due to its resistance to arc welding and superior heat dissipation during fast charging.
C17200 Beryllium Copper provides the "unbreakable" spring performance required for mission-critical aerospace connectors and landing gear bushings.
Specialized bronze alloys resistant to seawater corrosion and bio-fouling, used in underwater sensors and offshore energy platforms.
Oxygen-free copper strips used in solar cell busbars to ensure maximum electron flow and longevity in outdoor environments.
Precision-engineered tellurium copper electrodes and holders that withstand extreme temperatures while maintaining precise arc focus.
Modern procurement directors look for more than just a price list. They require a partner who understands the Total Cost of Ownership (TCO). At Kepai, we address these professional needs through:
Providing full material test reports (MTR), SGS certifications, and ultrasonic testing to ensure zero defects in large-scale batches.
Global export capabilities to Europe, North America, and Southeast Asia with optimized shipping routes to reduce lead times.
Our R&D team works directly with your engineers to select the exact alloy (e.g., C19160 vs C17500) based on your specific stress and conductivity loads.
Pure copper is difficult to machine because it is soft and "gummy." Tellurium copper (C14500) maintains 90-93% of pure copper's conductivity but adds free-cutting properties, allowing for much faster production of precision parts.
Because it offers the highest strength of any copper-based alloy (up to 1400 MPa tensile strength) while maintaining 20-30% IACS conductivity, making it irreplaceable for heavy-duty springs and connectors.
We use a specialized vacuum induction melting process and high-purity protective gas environments during casting to keep oxygen levels below 10ppm, preventing hydrogen embrittlement during high-temperature brazing.
Yes, all our copper alloys are manufactured to meet the latest environmental standards, and we provide third-party environmental certification for all exported products.
