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 facility spans 29,000 square meters, housing advanced production lines for cold and hot working processes.
We pride ourselves on providing OEM good processing that meets the rigorous demands of global exporters. Our core mission is to bridge the gap between traditional copper alloy limitations and the high-performance requirements of modern industries like New Energy Vehicles (NEV) and Aerospace.
Cold working, or work hardening, is performed below the recrystallization temperature. At Kepai, we utilize precision cold drawing and rolling to increase the yield strength and hardness of alloys like C51100 Phosphor Copper and C17200 Beryllium Copper. This process ensures superior surface finishes and tight dimensional tolerances required for precision connectors.
Hot working occurs above the recrystallization temperature, allowing for significant plastic deformation without fracturing. Our hot extrusion and forging processes for Tellurium Copper ensure a refined grain structure, eliminating internal porosity. This is critical for high-load components in power distribution and plasma cutting electrodes.
Choosing a China-based factory like Kepai offers more than just cost efficiency. It provides a comprehensive ecosystem of industrial synergy:
Proximity to high-purity copper refineries ensures consistent chemical composition, meeting ASTM and EN standards precisely.
Our independent R&D team can transition from alloy design to pilot production of new precipitation-hardening alloys in weeks, not months.
Whether you require wholesale C17300 or custom oxygen-free tellurium copper, our capacity scales to meet global procurement fluctuations.
For international exporters, compliance is the baseline of reliability. Kepai maintains a robust quality management framework:
| Standard | Description | Value to Buyer |
|---|---|---|
| ISO 9001:2015 | Quality Management Systems | Guaranteed batch-to-batch consistency. |
| ISO 14001:2015 | Environmental Management | Meets ESG requirements for sustainable sourcing. |
| OHSAS 45001 | Health and Safety | Ensures ethical production and factory longevity. |
| RoHS/REACH | Hazardous Substances Control | Essential for medical and electronics exports to EU/US. |
Our Localization Support includes technical documentation in multiple languages, deep understanding of regional alloy equivalents (e.g., DIN vs ASTM), and customized logistics solutions for DAP/DDP delivery.
The rise of 800V architectures in electric vehicles demands alloys with >85% IACS conductivity and high softening resistance. Our Oxygen-Free Tellurium Copper is becoming the gold standard for charging pins.
Connectors are getting smaller but carry higher power. Beryllium Copper (C17200) processed through advanced cold-working provides the high elastic modulus needed for ultra-small spring contacts.
Transitioning toward "Free-Cutting" alloys that are lead-free or low-lead, such as our Sulfur Copper (C14700), to meet evolving global environmental regulations.
Utilization of high-purity copper for its antimicrobial properties and MRI-compatible non-magnetic properties.
C18150 Chromium Zirconium Copper is used in rocket engine nozzles due to its high-temperature strength.
Marine-grade bronze alloys that resist seawater corrosion and bio-fouling for undersea sensors.
Partner with Sichuan Kepai for high-conductivity copper alloy solutions that redefine processing efficiency.
