PURPOSE:To obtain a magnetic Ni-Fe alloy with superior magnetic characteristics, high hardness and high magnetic flux density by blending Fe with a specified amount of Ni, Ti, C and Mg. CONSTITUTION:This magnetic Ni-Fe alloy consists of, by wt., 75-84.9% Ni, 0.5- 5% Ti, <0.03% C, 0.001-0.02% Mg and the balance Fe with impurities. The reason why the Ni content is restricted to the range is that superior permeability is obtd. Ti is added to increase the hardness, C is added as a deoxidizer, and Mg is added to improve the hot workability. Accordingly, when this magnetic Ni-Fe alloy is used as a material for a recording and reproducing magnetic head for a metallic tape, the recording and reproducing characteristics are enhanced. In addition, this alloy is suitable for use as a material for a magnetic head of a computer, VTR, etc. undergoing high-speed sliding. |
