Abstract (en)

[origin: EP0792943A1] Iron-nickel alloy has the composition (by wt.): 30-85%Ni + Co, 0-10% Co + Cu + Mn, 0-4% Mo + W + Cr, 0-2% V + Si, 0-1% Nb + Ta, 0.003-0.05% C, 0.003-0.15% Ti, 0.003-0.15% Ti + Zr + Hf, 0.001-0.015% (exclusive) S + Se + Te, 0-1% Nb + Ta + Ti + Al, balance Fe and impurities. Also claimed are: (i) a method of producing a cubic textured cold rolled strip of the above alloy; and (ii) a method of producing a toric magnetic core of the above alloy. Also claimed are: (i) a cold rolled strip of the above iron-nickel alloy, having a cubic recrystallisation texture of (100)(001) type; (ii) use of this strip for making a shadow mask for a CRT; and (iii) a toric magnetic core of the above alloy having a cubic texture. Preferably, the alloy contains 0.005-0.05% Ti, 0.001-0.025% Hf + Zr, 0.002-0.007% S, 0.005-0.02% C, 0.05-1% Mn and ≤ 0.05% Nb + Ta. The impurities preferably comprise less than 0.001% Mg, less than 0.0025% Ca, less than 0.05% Al, 0.0025% O, less than 0.005% N, less than 0.01% P and less than 0.01% total of Sc, Y, La, Ce, Pr, Nd and Sm.
