Understanding why C17200 (Alloy 25) is the ultimate choice for high-stress applications.
C1720 (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 compared to commercial copper alloys. Its tensile strength can exceed 200 ksi (1380 MPa), while maintaining electrical conductivity of approximately 20-30% IACS.
The unique performance of C1720 stems from the precipitation hardening (age hardening) process. This allows the material to be formed in a relatively soft state and then heat-treated to achieve exceptional elastic properties and fatigue resistance. This makes it irreplaceable for:
| Property | C1720 (Solution Treated + Aged) |
|---|---|
| Beryllium Content (%) | 1.80 - 2.00 |
| Tensile Strength (MPa) | 1140 - 1480 |
| Yield Strength (MPa) | 960 - 1280 |
| Hardness (HRC) | 36 - 42 |
| Electrical Conductivity (%) | 22 - 28 IACS |
| Thermal Conductivity | 105 W/mยทK |
How Kepai ensures competitive wholesale pricing with world-class quality standards.
Unlike middle-market suppliers, Kepai controls the entire process from vacuum induction melting to final precision drawing. This vertical integration reduces cost by 15-20% compared to Western counterparts.
We strictly adhere to ISO9001:2015, ISO14001:2015, and OHSAS 45001:2018. All C1720 materials are RoHS and REACH compliant, ensuring safe integration into consumer electronics and medical devices.
We provide localized warehousing support for high-volume partners, offering JIT (Just-In-Time) delivery and custom packaging solutions to prevent oxidation during maritime transit.
Where C1720 Becu makes the difference in performance and safety.
Used in MRI scanners and surgical instruments due to its non-magnetic properties and biocompatibility potential in specific alloy configurations.
C1720 provides the high cycle life required for battery connectors and charging interfaces in high-voltage EV architectures.
Ideal for landing gear bushings and actuator components where high strength-to-weight ratio and wear resistance are non-negotiable.
Excellent resistance to seawater corrosion and bio-fouling, making it the top choice for underwater sensors and housing.
Our oxygen-free tellurium copper and C1720 alloys are vital for electrodes and holders, extending consumable lifespan by up to 30%.
Micro-switches and relays utilize the fatigue resistance of Becu to ensure billions of switching cycles without failure.
What engineers and procurement officers need to know for 2025 and beyond.
As components get smaller, the demand for alloys with higher yield strength at thinner gauges increases. C1720 foil (0.05mm) is becoming a standard in smartphone connector designs.
Industry leaders are pivoting towards "Closed-Loop" recycling. Kepai is implementing green production processes to recover beryllium copper scrap, reducing the carbon footprint of wholesale supply.
Traditional TeCu is being replaced by Oxygen-Free versions for high-power EV charging. Our patented oxygen-free high-conductivity tellurium copper is at the forefront of this shift.
