Global Industry Trends & Growth DriversThe shift towards New Energy Vehicles (NEV) requires connectors that can handle high currents with minimal heat generation. Our C14500 Tellurium Copper offers 85%+ IACS conductivity, making it the industry standard for fast-charging pins.
Beryllium Copper (C17200) remains irreplaceable in aerospace due to its non-sparking properties, high strength (up to 1400 MPa), and resistance to fatigue. It is the "muscle" behind landing gear bushings and flight control systems.
Industry 4.0 demands precision. Lead Bronze and Free-Cutting Brass (C36000) allow for ultra-high-speed CNC machining with minimal tool wear, reducing the carbon footprint of mass production.
The highest strength of all copper-based alloys. Ultimate tensile strength can exceed 200 ksi. Perfect for precision spring clips and highly reliable conductive springs.
Combines high electrical/thermal conductivity with excellent machinability. Ideal for plasma cutting nozzles and welding torch tips where heat dissipation is critical.
A nickel-silicon precipitation strengthened alloy. Features outstanding softening resistance and high-temperature stability for industrial switchgears.
Global procurement heads are currently facing a "Trilemma": Quality vs. Speed vs. Cost. Sichuan Kepai addresses this through our integrated production system. Unlike traditional exporters who act as middlemen, Kepai controls the process from raw material smelting to precision extrusion. This "Vertical Integration" ensures:
From the depths of the ocean to the vacuum of space, our materials are engineered for extremes.
Utilizing copper's natural antimicrobial properties for surgical instruments and MRI components where interference must be zero.
High-strength bronze alloys that resist seawater corrosion and biological fouling for underwater sensors and offshore power grids.
Photovoltaic storage systems and wind turbine grounding systems rely on Kepai’s OFT copper for maximum energy efficiency.
Our company has passed ISO9001:2015, ISO14001:2015, and OHSAS 45001:2018. This triad of certification reflects our commitment to international standards in quality, environmental stewardship, and occupational health.
Expert Insight: The development of Oxygen-Free Tellurium Copper (OFT) was a response to the "Hydrogen Embrittlement" issue found in standard tellurium copper. Our R&D team successfully reduced oxygen content to below 10ppm while maintaining high conductivity.
Our tellurium copper features small, uniformly dispersed tellurium particles that act as chip breakers. This allows for higher spindle speeds and smoother surface finishes, significantly reducing "tool gummy" issues associated with pure copper.
Yes. Through precipitation hardening (aging), we can provide C17200 and C17300 in various tempers (Quarter Hard, Half Hard, Full Hard) to match your specific elastic modulus and tensile strength requirements.
By maintaining a 29,000 sqm facility with large-scale raw material inventory and an independent R&D production cycle, we buffer our clients against the price surges and shortages often seen in the LME (London Metal Exchange).
While containing lead for machinability, our alloys are strictly controlled to meet the specific exemptions under RoHS for copper alloys, ensuring they are safe for global industrial export.
