Are cupronickels magnetic? Copper Nickel Alloys
Cupronickels have a very low magnetic permeability <1.01. Magnetic permeability indicates the ease with which an external magnetic field can create a magnetic force of attraction in the metal. By this measure, cupronickels such as Hiduron 130 (DTD900/4805, 2.1504) are considered non-magnetic, which is a useful property for applications in valves, sensors and connectors.
