CDA 172 (C17200), often referred to as Beryllium Copper Alloy 25, is the most commonly utilized beryllium copper alloy and is noted for exhibiting the highest strength and hardness relative to commercial copper alloys. As a premier wholesale CDA 172 Beryllium Copper supplier, Kepai New Material provides this alloy which combines tensile strength exceeding 200 ksi and hardness approaching Rockwell C45, while maintaining excellent thermal and electrical conductivity.
Unlike standard copper alloys, CDA 172 gains its exceptional properties through precipitation hardening (age hardening). The microscopic structure features a copper matrix with fine beryllium-rich particles that block dislocation movement, creating a material that can withstand extreme mechanical stress without deformation. This is why it is indispensable for precision industrial components.
Currently, the global demand for CDA 172 is surging due to the miniaturization of electronics and the electrification of transportation. From the depths of oil wells in the North Sea to the intricate connectors in 5G base stations in Shenzhen, CDA 172 is the silent engine of modern infrastructure. Leading companies in North America, Europe, and Asia-Pacific are increasingly looking for supply chain resilience to mitigate risks associated with raw material volatility.
Used in landing gear bushings, fasteners, and instrumentation where non-magnetic and anti-galling properties are critical under extreme loads.
Critical for EV battery connectors and high-reliability sensors that must operate in high-vibration and high-temperature environments.
Non-sparking and corrosion-resistant tools and drilling components that require high fatigue strength in sour gas environments.
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 special copper alloys. Our facility spans 29,000 square meters, housing advanced production lines for oxygen-free tellurium copper and beryllium copper.
Our Independent R&D team has mastered the art of vertical integration—from melting and casting to extrusion and finishing. This ensures that every kilogram of CDA 172 Beryllium Copper we export meets international standards like ASTM B194 and ASTM B196.
Choosing a China-based manufacturer like Kepai offers significant strategic advantages beyond cost. Our efficiency is built on three pillars:
We control the entire process from raw material sourcing to final heat treatment, reducing lead times by up to 30% compared to Western competitors.
Our R&D team can develop custom copper alloy compositions for specific engineering challenges within weeks, not months.
With 29,000 sqm of floor space, we can handle wholesale orders from several hundred kilograms to dozens of tons with consistent quality.
The copper alloy industry is undergoing a "Green & Smart" transformation. Kepai is at the forefront of this evolution:
We understand that CDA 172 Beryllium Copper is a regulated material. Kepai ensures full compliance with international safety and environmental standards:
ISO9001:2015, ISO14001:2015, and OHSAS 45001:2018. We provide full traceability and mill test reports (MTRs) for every shipment.
Strategic export experience to North America, Europe, and SE Asia with localized documentation support for customs and tariff optimization.
Comprehensive SDS (Safety Data Sheets) provided to guide clients on safe machining practices to manage beryllium dust effectively.
