Beryllium Copper Alloy 172, also known by the UNS designation C17200, represents the pinnacle of copper-based metallurgy. As a precipitation-hardening alloy, it achieves the highest strength and hardness of any copper alloy on the market today. At Kepai New Materials, our C17200 is engineered to meet and exceed international standards including ASTM B194, B196, and AMS 4533.
What sets Alloy 172 apart is its unique combination of mechanical strength (comparable to many high-strength steels) and electrical/thermal conductivity. It is non-magnetic, non-sparking, and possesses exceptional fatigue resistance—making it indispensable for hazardous and high-stress environments.
Ultimate tensile strength exceeding 200 ksi (1380 MPa) and hardness reaching Rockwell C45, providing durability in extreme load-bearing applications.
Retains 20-30% IACS conductivity while maintaining steel-like strength, ideal for high-reliability electrical connectors and switches.
Excellent resistance to stress relaxation and fatigue, ensuring long-term reliability for springs, bellows, and diaphragms.
Maintains mechanical properties across a wide temperature range, essential for downhole oil & gas tools and aerospace components.
The global demand for Beryllium Copper Alloy 172 is undergoing a significant transformation. As industries move toward Miniaturization and Electrification, the need for materials that can handle higher currents in smaller footprints has surged.
With the explosion of AI and 5G, C17200 is the preferred material for test sockets and burn-in connectors due to its ability to maintain contact force at elevated temperatures.
The shift to 800V architectures in electric vehicles requires high-strength conductive materials for battery interconnects and charging terminals where safety is paramount.
Offshore and deep-well drilling utilize C17200 for non-magnetic drill collars and instrumentation housings that must withstand corrosive seawater and high pressures.
Kepai New Materials does not just sell alloys; we provide integrated metallurgical solutions that solve complex engineering challenges.
Providing AMS-certified C17200 for landing gear bushings, actuator bearings, and electronic countermeasure components. Our materials offer the highest reliability where failure is not an option.
Non-magnetic properties of Beryllium Copper are vital for MRI equipment. Its biocompatibility and sterilization resilience make it ideal for surgical tools and robotic surgical arm connectors.
Resistance welding electrodes and plunger tips for die casting. Our alloys extend the service life of tooling, reducing downtime and operational costs for Tier 1 automotive suppliers.
As a global exporter, Kepai adheres to stringent international standards. We understand the regulatory landscapes of North America, Europe, and Asia-Pacific.
Kepai is committed to the "Next-Gen Materials" roadmap. While C17200 remains the industry standard, our R&D team is focused on three primary areas for the 2025-2030 horizon:
Utilizing proprietary vacuum melting techniques to produce ultra-fine grain C17200, which offers improved isotropic properties and superior surface finish for micro-machined parts.
Developing eco-friendly recycling processes for beryllium-containing scrap to reduce the carbon footprint of our manufacturing cycle without compromising material purity.
Researching Copper-Nickel-Silicon-Beryllium (C17510) optimizations to offer a middle-ground solution with even higher conductivity (45-60% IACS) for high-frequency power electronics.
The ultimate high-performance alloy. Tensile strength up to 1380 MPa. Used in heavy-duty connectors, springs, and aerospace bushings.
A variation of C17200 with added lead for enhanced machinability, allowing for high-speed automated production of complex precision parts.
Optimized for thermal conductivity and moderate strength. Widely used in resistance welding electrodes and electrical switchgear.
Kepai’s flagship innovation. Combines ultra-high conductivity (>98% IACS) with excellent free-cutting performance for EV charging pins.
