Engineered for high-strength and extreme thermal conductivity.
The demand for Low-temperature machinable beryllium copper is surging due to the expansion of quantum computing, liquid hydrogen fuel systems, and deep-space exploration. These alloys provide non-magnetic properties and maintain ductility at near-absolute zero temperatures.
Beryllium Copper (CuBe) stands out by offering a unique "precipitation hardening" mechanism. Unlike traditional alloys, its microstructure can be tailored to achieve tensile strengths exceeding 1400 MPa while retaining electrical conductivity, making it indispensable for high-reliability connectors.
Kepai New Material utilizes digital twin technology and automated precision casting to ensure batch-to-batch consistency. Our "Factory 4.0" approach reduces waste by 15% and ensures that free-cutting alloys like C17300 meet the tightest tolerances required by Swiss-style machining.
In the realm of high-performance metallurgy, Low-temperature machinable beryllium copper (specifically variants like leaded C17300 or high-purity C17200) represents the pinnacle of copper alloy engineering. As industries move toward extreme environments—whether it be the sub-zero temperatures of arctic drilling or the cryogenic cooling systems of superconducting magnets—the material choice becomes critical.
Traditional high-strength beryllium copper is notoriously difficult to machine due to its hardness. However, "Machinable" grades incorporate trace elements that act as chip breakers without compromising the alloy's structural integrity. This allows for high-speed production of complex parts like probe pins, coaxial connectors, and non-sparking safety tools.
Global procurement directors are increasingly looking for reliable Chinese suppliers who offer more than just low costs. The shift is toward "Information Gain" and "Supply Chain Transparency." Kepai's integration from R&D to final export provides a resilient buffer against global market volatility, ensuring that high-tech industries in Europe and North America have access to critical materials without disruption.
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 providing solutions that meet the rigorous E-E-A-T standards of the global manufacturing industry.
Our materials are certified for the most demanding industrial applications.
C17200 beryllium copper provides the highest strength of all available copper-beryllium alloys. It has electrical and thermal conductivity considerably greater than other high-strength copper alloys with an ultimate tensile strength that can exceed 200 ksi (1380 MPa).
C17300 is a high-performance precipitation-hardening copper alloy. It is made by adding a small amount of lead to C17200 to enhance the material's cutting performance, while maintaining excellent strength and conductivity. Widely used in precision industrial fixtures.
In the high-speed development fields such as new energy vehicles, traditional tellurium copper faced a dilemma. Kepai's OFT copper achieves superior conductivity and processing performance, breaking the limits of conventional materials.
