C17500: Stronger corrosion resistance than copper, with a yield strength of 980Mpa! C17500 is a beryllium cobalt copper alloy that has a stronger medium yield strength compared to C17200. After aging treatment, its strength can reach 980Mpa.
In addition, its conductivity is 45% -65% of pure copper. C17500 is widely used in fuses, fasteners, springs, switch components, resistance spot welding electrode heads, electrical connectors, wires, and other aspects. In terms of chemical composition, the main components of C17500 include copper, beryllium, cobalt, and aluminum.
Its specific chemical composition is as follows:
Copper (Cu): surplus
Beryllium (Be): 0.4-1.7%
Cobalt (Co): 2.4-2.7%
Aluminum(Al): ≤ 0.20%
Silicon (Si): ≤ 0.20%
Iron (Fe): ≤ 0.10%
In terms of mechanical properties, C17500 has excellent strength and toughness. After aging treatment, its yield strength can reach 980Mpa, and it has good ductility and plasticity. In addition, it also has excellent antioxidant performance and chemical stability, exhibiting high chemical stability in the atmosphere, fresh water, and seawater. In terms of execution standards, C17500 meets the following standards: American standards: ASTM B441, ASTM B534 C17500 is a high-performance beryllium cobalt copper alloy, and its strength and conductivity can play a good role in various application scenarios. Its chemical stability and antioxidant performance are also one of the reasons why it is widely used.
