Established in May 2017, Sichuan Kepai New Materials Co., Ltd. has rapidly ascended as a high-tech titan in the specialized copper alloy sector. Operating from a 29,000 m² state-of-the-art facility, we integrate R&D, advanced smelting, and precision processing to serve over 1,000 global clients.
Our core expertise lies in the "free-cutting" and "high-conductivity" frontier—specifically Tellurium Copper and high-performance Cartridge Brass. By securing over 30 patent certificates and adhering to IATF 16949 standards, we don't just supply metal; we engineer technical solutions that mitigate conductivity loss and enhance machining efficiency.
The global demand for Cartridge Brass (C26000 / CuZn30) is currently undergoing a transformative shift. Traditionally the backbone of the ammunition and automotive radiator industries, this 70/30 copper-zinc alloy is seeing surged interest in the Renewable Energy and Electric Vehicle (EV) sectors due to its superior ductility and corrosion resistance.
Procurement directors are currently facing triple-threat challenges: price volatility in the LME (London Metal Exchange), stringent environmental regulations (RoHS/REACH compliance), and the need for Information Gain in material data sheets. Kepai addresses these by providing transparent traceability and micro-alloying enhancements that improve the traditional tensile limits of C26000.
Transitioning from traditional melting to vacuum induction melting to ensure oxygen levels below 5ppm, enhancing welding stability in aerospace applications.
Developing ultra-small grain C26000 variants for complex deep-drawing processes, reducing the "orange peel" effect in precision cases.
Our roadmap emphasizes the elimination of hazardous impurities, aligning with the EU's 2030 sustainability goals for electronics and potable water systems.
Antimicrobial copper surfaces and precision-machined brass components for ventilators and surgical imaging equipment.
High-conductivity tellurium copper busbars and connectors designed for high-voltage battery management systems.
Beryllium copper and cartridge brass solutions for signal transmission and structural integrity in harsh environments.
Corrosion-resistant alloys for seawater cooling systems and offshore energy infrastructure.
In the high-stakes world of wholesale cartridge brass supply, "Reliability" (the 'R' in E-E-A-T) is defined by compliance. Kepai New Material operates under a rigorous quality management umbrella:
To support our international clients in North America, Europe, and Southeast Asia, we provide comprehensive localized technical support. This includes material substitution analysis, failure mode analysis (FMEA), and rapid prototyping of custom alloys to meet localized national standards (ASTM, DIN, JIS).
C26000 offers an optimal 70/30 copper-to-zinc ratio, providing the best combination of strength and ductility. It is the gold standard for deep-drawing applications, where the metal must be stretched without thinning or fracturing.
While pure copper is difficult to machine (it's "gummy"), adding Tellurium maintains 90%+ conductivity while drastically increasing the "Machinability Rating" from 20 to 85. This results in faster production and longer tool life.
Yes. We specialize in environmentally friendly production, ensuring all our alloys meet strict global chemical restrictions, making them safe for consumer electronics and medical devices.
Absolutely. Our in-house R&D team can adjust alloy percentages (Copper, Zinc, Tellurium, Beryllium) to meet specific thermal expansion or tensile strength requirements for unique industrial applications.
