A Fe-Cu alloy plate having an alloy structure excellent in homogeneity

摘要

An iron-copper alloy plate with an alloy structure excellent in homogeneity, produced by the continuous thin plate casting process, and usable as the material of electronic and magnetic components, said alloy comprising 20 to 90 % of Cu, 1 to 10 % of Cr, 0 to 10 % of Mo, and at least one element selected from the group consisting of Al, Sc, Y, La, Si, Ti, Zr and Hf in an amount ranging from the value calculated according to formula (I) up to 10 %, the balance being substantially Fe wherein α = 1, and β = 51 - [% Cu] when Cu = 20 - 50 %, or β = -19 + 0.4 [% Cu] when Cu = 50 - 90 %. Also boron and/or carbon can exhibit a similar effect to that of the abovementioned aluminum and the like.
