C17510 copper is a high-strength, heat-treatable copper alloy that contains approximately 2% beryllium and 0.5% cobalt. It is also known as Beryllium Cobalt Copper or BeCuCo.C17510 copper has excellent strength, hardness, and conductivity, as well as good wear resistance and thermal stability. Its high strength and fatigue resistance make it ideal for use in high-stress applications such as springs, electrical contacts, and connectors.This alloy has good resistance to corrosion and is often used in marine environments and other applications where exposure to seawater or other corrosive media is a concern.
