Curie temperature of nickel
WebFor example, alloying nickel with copper will reduce the Curie temperature–at around 65 wt% nickel, the Curie temperature is at 0°C, so it would be magnetic in your freezer, but not at room temperature. U.S. Nickel coins are only 25 wt% nickel, so you can imagine that their Curie temperature drops below absolute zero, until it isn’t ...
