C17510 Copper

Beryllium copper (Class 3)

C17510 copper (copper-nickel-beryllium, CuNi2Be) is a heat-treatable alloy that combines high electrical and thermal conductivity with good mechanical strength. It offers considerably higher conductivity than C17200, making it ideal for components that require strength and efficient transfer of electricity or heat.
