Silver Bearing Copper (C11300) is a high-purity copper alloy containing a small addition of silver, typically in the range of 0.03%–0.12%.
The silver addition improves softening resistance and thermal stability while maintaining excellent electrical and thermal conductivity. This makes C11300 ideal for high-temperature electrical and power applications.
Key Characteristics
✔ Maintains over 99% IACS electrical conductivity
✔ Enhanced resistance to softening at elevated temperatures
✔ Excellent thermal conductivity for heat-intensive applications
✔ Good formability, weldability, and fabrication characteristics
Electrical & Thermal Performance
Silver Bearing Copper retains nearly pure copper conductivity while offering superior performance under continuous thermal loading.
It is widely used where standard copper grades soften or lose mechanical strength during prolonged high-temperature service.
Refining & Metallurgical Properties
C11300 is produced through controlled refining processes to ensure very high copper purity with low oxygen content.
Silver is alloyed in precise micro-percentages to improve resistance to recrystallization and softening during processing and service.
The controlled refining process minimizes impurities, enhancing corrosion resistance and extending service life in demanding electrical environments.
