Ensuring maximum yield and electrical integrity for precision manufacturing.
Established in May 2017, Sichuan Kepai New Materials Co., Ltd. has rapidly emerged as a global authority in the metallurgy of specialty copper alloys. With a 29,000 sqm production facility, we specialize in High Conductivity and High Strength Free-Cutting Tellurium Copper. Our technical ethos is built upon the "High Yield Rate" philosophy—minimizing material waste while maximizing component performance for our 1000+ global clients.
The industry trend for 2024 and beyond focuses on Miniaturization and Green Manufacturing. High-yield suppliers are no longer just material providers; we are efficiency partners. By utilizing Oxygen-Free Tellurium Copper (OFT), manufacturers can achieve significantly lower rejection rates in high-speed CNC machining compared to traditional ETP (Electrolytic Tough Pitch) copper.
Understanding the "Search Intent" of modern procurement officers in the high-tech sector.
As a leading exporter, Kepai maintains strategic market distribution across North America, Europe, and Southeast Asia, ensuring reliable lead times for critical infrastructure.
Meeting ISO 9001:2015, ISO 14001:2015, and OHSAS 45001 standards. Our materials are fully RoHS and REACH compliant, essential for the medical and aerospace sectors.
From custom copper-nickel-beryllium alloys to specific tellurium ratios, we align our production lines with your high-yield performance benchmarks.

Innovation History
Engineering materials that define the boundaries of what is possible in modern technology.
Transitioning from traditional metallurgy to AI-driven material science.
Refining our melting processes to achieve oxygen levels below 5ppm, enhancing the weldability and ductility of our tellurium copper series (C14500 and OFT).
Implementing AI-driven simulation to predict the precipitation behavior of beryllium and cobalt atoms, allowing for bespoke hardness levels without sacrificing conductivity.
Developing closed-loop recycling for high-value scrap (like Beryllium Copper) to support the "Green Supply Chain" requirements of global tech giants.
What is Information Gain? It is the unique insight we provide: Traditional tellurium copper often sacrifices conductivity for machinability. Kepai’s proprietary OFT (Oxygen-Free Tellurium) process utilizes a "non-deoxidizing" approach that maintains the IACS (International Annealed Copper Standard) at levels exceeding 93%, while maintaining a machinability rating of 85. This duality is the core of our "High Yield Rate" promise—faster production with fewer electrical losses.
By adding a trace amount of lead to the C17200 matrix, we produce C17300. This modification significantly reduces tool wear during the production of micro-connectors for AI servers, effectively increasing the "yield rate" of the manufacturing plant by 15-20%.
Designed for the welding industry, this alloy maintains its hardness at elevated temperatures. This is vital for high-yield resistance welding electrodes in the automotive assembly lines, where downtime for electrode replacement is a major cost driver.
Global shipping available for these high-performance grades.
Answering technical queries for procurement and engineering teams.
A: It refers to both the consistency of the raw material (minimizing defects like porosity or inclusions) and its machinability. High-yield materials allow for faster CNC speeds and longer tool life, directly increasing the number of finished parts per unit of time.
A: Oxygen-free variants eliminate the risk of hydrogen embrittlement during brazing or welding processes. It also provides superior ductility, which is essential for components undergoing complex forming after machining.
A: Every batch undergoes rigorous testing including spectral analysis for chemical composition, ultrasonic testing for internal integrity, and conductivity measurement via Eddy current methods. We provide full mill test certificates (MTC) with every export.
A: Yes, sulfur copper (C14700) is a preferred alternative to leaded brass in certain applications because sulfur acts as a lubricant for machining without the environmental baggage of heavy lead content, aiding in green compliance.
