Top-tier Beryllium Copper and special alloys for global precision engineering.
Analyzing the indispensable role of Beryllium Copper in Modern Industry 4.0
UNS C17200, often referred to as Alloy 25, stands as the most commonly utilized beryllium copper alloy and is noted for exhibiting the highest strength and hardness relative to commercial copper alloys. In the current global industrial landscape, the demand for C17200 has shifted from traditional electrical components to high-stakes sectors including 5G infrastructure, aerospace actuators, and subsea oil and gas exploration equipment.
"Beryllium copper combines the strength of alloy steel with the thermal conductivity of aluminum, making it the 'King of Non-Ferrous Metals' in critical engineering."
The global market for C17200 is characterized by a drive toward miniaturization. As electronic connectors become smaller, the material must maintain extreme fatigue strength and conductivity. Sichuan Kepai New Materials Co., Ltd. has positioned itself at the forefront of this shift, integrating R&D with high-scale manufacturing to meet the precision requirements of the next decade.
C17200 offers ultimate tensile strength exceeding 200 ksi (1380 MPa) while maintaining 20% IACS conductivity. This unique balance prevents component failure in high-stress thermal environments.
In Marine and Subsea environments, the alloy forms a protective surface oxide layer, resisting stress corrosion cracking and hydrogen embrittlement better than most high-strength steels.
While high-strength, C17200 (and its leaded variant C17300) offers excellent formability in the annealed state, allowing for complex geometries before the final age-hardening process.
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. With a 29,000 m² factory footprint and 30+ patent certificates, we bridge the gap between material science and industrial application.

How Kepai delivers information gain and cost-performance for global exporters.
Unlike fragmented manufacturers, Chinese factories like Kepai integrate the entire lifecycle—from alloying and casting to precision extrusion and heat treatment. This reduces the carbon footprint and lead times by up to 30%.
Utilizing IATF 16949 standards, we implement real-time spectroscopic analysis for every batch of C17200, ensuring chemical consistency that exceeds ASTM and EN international standards.
Whether you require copper foil, rods, or tubes, our production lines are agile. We offer "Small Batch, High Variety" (SMED) capabilities that are often unavailable in Western markets.
Where Beryllium Copper UNS C17200 is making a difference today.
Non-magnetic properties of C17200 are critical for MRI equipment components and surgical tools where precision and safety are paramount.
The rise of EV charging infrastructure demands alloys that can withstand high current and mechanical wear—C17200 is the industry's answer for durable connectors.
Landing gear bushings and cockpit instrumentation rely on the fatigue resistance of beryllium bronze to ensure long-term reliability in extreme conditions.
Resistance to seawater corrosion makes our alloys ideal for underwater sensor housings and telecommunications cable repeaters.
The future of the Beryllium Copper market is tethered to Sustainability and Material Innovation. We are seeing a 15% annual growth in demand for lead-free alternatives and high-purity oxygen-free copper variants. Procurement managers are no longer just looking for the lowest price; they are seeking "Total Value of Ownership" (TVO)—reliability, compliance, and material traceability.
Kepai boasts an independent R&D team and production system. Our innovation in Oxygen-free high conductivity tellurium copper has set new industry standards, offering lower impurity levels than traditional materials.
Expert answers to the most common technical and sourcing questions.
C17200 is the standard high-strength alloy. C17300 is essentially C17200 with a small addition of lead (0.2-0.6%) to significantly improve machinability on automatic screw machines without sacrificing mechanical properties.
We demonstrate Experience through our established history since 2017, Expertise via our 30+ patents, Authoritativeness by participating in industry standard formulations, and Trustworthiness through ISO 9001/14001 and IATF 16949 certifications.
C17200 is typically age-hardened at 315-330°C for 2-3 hours depending on the required temper (TF00 or TH04). Our factory provides pre-hardened material or guidance on on-site treatment.
Yes. Our 29,000 m² facility is equipped for custom extrusion and precision rolling, allowing us to export non-standard rods, wires, and foils tailored to specific client blueprints.
While phosphor bronze is cost-effective, beryllium copper provides much higher fatigue strength and higher conductivity, allowing connectors to be made thinner and more resilient under repeated stress.
