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.
We focus on high conductivity and high strength free cutting tellurium copper and other copper alloys, providing innovative solutions for global industrial challenges.
Our company has established its own independent R&D team, equipped with a complete production system and mature production technology. This allows us to have deep knowledge in the production of traditional and advanced copper alloys.
We have developed a new type of highly conductive oxygen-free tellurium copper. Compared with traditional copper tellurium, this material has lower impurities and superior reliability.
In addition to a high share of the domestic copper alloy market, Kepai has exported to overseas clients with a high reputation. We participate in the formulation of relevant industry standards, enhancing market influence globally.
C10100, commonly known as Oxygen-Free Electronic (OFE) copper, is the highest purity copper grade commercially available, produced under strict atmospheric control to ensure a minimum copper content of 99.99%. As a premier OEM C10100 company, Sichuan Kepai adheres to ASTM B170 standards, eliminating oxygen to levels below 5 ppm (parts per million). This lack of residual deoxidants and high purity results in a material with 101% IACS electrical conductivity and exceptional thermal properties.
China has evolved from a mass-producer to a high-tech hub for metallurgical innovation. Choosing a C10100 manufacturer in China like Sichuan Kepai offers several strategic advantages:
From raw electrolytic copper cathode procurement to final CNC machining, our 29,000 sqm facility in Sichuan reduces lead times and logistical overhead for global enterprises.
We leverage localized economies of scale and advanced automation to provide aerospace-grade C10100 tubes, foils, and bars at competitive OEM prices without sacrificing quality.
Unlike standard stockists, Sichuan Kepai provides custom alloy formulations, such as our proprietary high-conductivity tellurium copper, catering to specific vacuum electronic needs.
In the era of 5G, Electric Vehicles (EV), and Renewable Energy, the demand for C10100 has shifted. Companies are no longer looking for "just copper"; they require Information Gain regarding material lifecycle, hydrogen embrittlement resistance, and vacuum integrity. Kepai provides macro industry solutions, including:
Utilizing the anti-microbial and high-thermal properties for MRI shielding and advanced surgical instrumentation.
C10100 and specialized tellurium copper are the backbone of EV charging connectors and battery management systems (BMS).
Vacuum-grade C10100 is essential for waveguides and satellite communication components where outgassing must be avoided.
Copper alloys provide natural resistance to seawater corrosion and bio-fouling for undersea sensors and cables.
Passed ISO9001:2015, ISO14001:2015, and OHSAS 45001:2018, ensuring international reliability.
Use of environmentally friendly materials and processes to produce sustainable green products.
Owned intellectual property for oxygen-free high-conductivity tellurium copper alloys.
Full-spectrum testing for conductivity, hardness, and chemical composition in every batch.
C10100 (Oxygen-Free Electronic) is 99.99% pure with nearly no oxygen, making it resistant to hydrogen embrittlement. C11000 (ETP Copper) contains a small amount of oxygen, which is suitable for standard electrical use but not for vacuum environments or high-temperature brazing.
Yes. As a leading OEM factory, we specialize in customizing tellurium copper, beryllium copper, and sulfur copper alloys to meet specific conductivity and machinability requirements for our global clients.
China-based manufacturers like Sichuan Kepai offer a unique combination of high-tech production capabilities, rapid R&D iteration, and competitive global pricing due to our integrated 29,000 sqm production base.
We use state-of-the-art eddy current testing and chemical analysis to ensure our C10100 meets or exceeds 101% IACS conductivity standards.
Expert technical consulting and global supply for C10100 and specialized copper alloys.
