AgWCC contact materials represent a breakthrough in electrical contact technology, engineered to deliver optimal performance while significantly reducing material costs. Our advanced AgWCC/Cu composite contacts feature an innovative layered architecture that combines the best properties of two distinct materials. The working surface retains the premium AgWCC alloy, preserving its inherent low contact resistance, exceptional anti-welding characteristics, and reliable self-lubricating properties. The backing layer utilizes high-conductivity copper, providing robust structural support and excellent electrical transmission capabilities.
