Is copper magnetic? Copper Alloys
Copper and alloys primarily based upon copper are considered non-magnetic. This is an important physical property of Hiduron 130, a high-strength copper nickel alloy used in subsea applications, such as connectors and couplings, as well as valve trim. As a copper-based alloy it is resistant to fouling and galling, making it suitable for applications which see long periods on inactivity, but which are then are required to operate without sticking. Therefore, avoiding the potential influence of magnetic coupling is supportive of such applications.
