Specializing in high conductivity and high strength free-cutting tellurium copper and special beryllium alloys. Sichuan Kepai is a high-tech private leader established to bridge the gap between material performance and industrial demand.
Beyond a high domestic market share, Kepai’s export reach covers precision manufacturing hubs worldwide, offering materials that comply with ISO9001, ISO14001, and IATF 16949 standards.
Our independent R&D team continuously optimizes precipitation-hardened alloys, specifically C17000 and C17200, ensuring peak electrical conductivity without sacrificing mechanical durability.
C17000 Beryllium Copper (Alloy 165) represents a pinnacle in copper-based metallurgy, specifically engineered for applications where high strength is required but conductivity remains a priority. Unlike standard copper, C17000 gains its extraordinary properties through a process known as precipitation hardening. As a leading manufacturer, we provide C17000 that meets the stringent requirements of ASTM B194, B196, and SAE J461.
In the current global industrial landscape, the demand for C17000 is driven by the shift toward electrification and miniaturization. From 5G telecommunications to the next generation of Aerospace connectors, C17000 offers a yield strength that can exceed 100,000 psi while maintaining 22-25% IACS conductivity. This unique combination makes it indispensable in environments subject to high stress and electromagnetic interference.
The global beryllium copper market is currently undergoing a structural transformation. Leading factories are moving toward more sustainable production methods while focusing on "Information Gain"—the ability to provide not just a raw material, but a metallurgical solution.
Navigating the supply chain of beryllium copper requires deep knowledge of international compliance. At Sichuan Kepai, our localized support ensures that customers in Europe, North America, and Southeast Asia receive products that are fully compliant with RoHS 3.0 and REACH regulations. Our internal quality control systems track every melt to its origin, providing full transparency—a critical factor for high-reliability industries like medical device manufacturing and defense.
While C17000 remains the industry standard, research is pushing toward alloys that deliver similar hardness with lower beryllium content to simplify environmental handling while maintaining the signature elastic properties.
By controlling the aging process at the nanometer scale, we are achieving higher uniformity in material grain structure, leading to longer fatigue life in cyclic loading applications.
Implementing machine learning algorithms in our foundries to predict cooling rates and minimize internal stresses, ensuring every batch of C17000 is optimized for precision machining.
C17000 contains slightly less beryllium (1.6-1.79%) compared to C17200 (1.8-2.0%). While C17200 offers the absolute highest strength, C17000 provides a better balance for applications requiring significant cold work before final aging.
Yes, once the alloy is formed and heat-treated, it is chemically stable and non-toxic. It is widely used in diagnostic equipment due to its non-magnetic properties.
C17000 is typically precipitation hardened (aged) at temperatures between 600°F and 900°F (315°C to 480°C) depending on the desired hardness and conductivity levels.
We utilize advanced spectrometry for chemical analysis and rigorous mechanical testing (tensile, hardness, conductivity) for every production lot to ensure compliance with global standards.
