Curie Points of Ferromagnetic Elements Iron - 770 C Cobalt - 1131 C Nickel - 358 C Gadolinium - 16 C" 1404.2 K: Magnetically Assisted Gasification. Properties of Nickel 200, the commercially pure grade (99.6% Ni): Curie Temperature - 360°C" 360 °C The Curie temperature or Curie point is a temperature at which a material loses its magnetic characteristics such as an ability to attract other magnets. "Cobalt, with a Curie temperature of 1121 C, is clearly superior from the standpoint of high temperature operation." …characteristic temperature T c called the Curie temperature. For temperatures above T c the crystal is not… The Curie temperatures for three common ferromagnetics—iron, cobalt, and nickel—are 1,043 K; 1,394 K; and 631 K, respectively. For temperatures below T c the magnetic moments of the ions are aligned and the crystal is magnetic. UMPQUA Research Company.
