Explore our custom-engineered metallurgical solutions designed for high conductivity, strength, and thermal efficiency.
C17500 Beryllium Copper (UNS C17500) represents a pinnacle class of precipitation-hardening copper-based alloys designed specifically to deliver an exceptional balance between high electrical and thermal conductivity and mechanical strength. Classified under RWMA Class 3, C17500 is alloyed primarily with Cobalt (1.40% to 2.70%) and Beryllium (0.40% to 0.70%), allowing it to reach tensile strengths exceeding 700 MPa while maintaining up to 60% IACS (International Annealed Copper Standard) conductivity.
OEM components manufactured from C17500 must strictly conform to globally recognized metallurgical specifications to guarantee predictable performance under stress. The primary industrial standards governing C17500 manufacturing processes include:
| Alloy (UNS/Designation) | Beryllium Content (%) | Thermal Conductivity (W/m·K) | Electrical Conductivity (% IACS) | Tensile Strength (MPa) | Hardness (HRB/HRC) |
|---|---|---|---|---|---|
| C17500 (Be-Co-Cu) | 0.40% - 0.70% | 240 - 260 | 45% - 60% | 680 - 820 | 90 - 100 HRB |
| C17200 (High-Strength Be) | 1.80% - 2.00% | 105 - 130 | 17% - 25% | 1100 - 1350 | 36 - 42 HRC |
| C18150 (Cr-Zr-Cu) | 0.00% | 320 - 340 | 75% - 85% | 450 - 550 | 70 - 85 HRB |
| C14500 (Tellurium-Cu) | 0.00% | 350 - 370 | 90% - 98% | 250 - 320 | 40 - 55 HRB |
C17500 plays a foundational role across primary industrial sectors, providing unique solutions to engineering challenges where high heat and high currents meet.
Crucial for manufacturing high-current battery terminals, electric vehicle relays, charging connectors, and resistance welding electrodes used in automated robotic body assembly lines. C17500 maintains its mechanical stability under severe cyclic thermal stress.
Used extensively in high-reliability military-grade connectors, avionics instrumentation components, and heat sinks where thermal dissipation must be executed rapidly under severe weight constraints. Its excellent corrosion resistance enhances lifespan in marine conditions.
Supports modern telecommunications grids by serving as contact terminals, coaxial connector pins, and transmitter parts. It efficiently conducts high-frequency signals while continuously managing heat dissipation to prevent system degradation.
The global demand for C17500 Beryllium Copper is driven by the rapid growth of automation, structural transitions toward electric vehicles (EV), and high-voltage power networks. With strict international regulatory standards like RoHS (Restriction of Hazardous Substances) and REACH governing chemical formulations, top-tier OEM manufacturers must balance performance requirements with ecological compliance.
