Generally speaking, the properties of magnetic alloys are mainly dependent on the purity. The properties of 50% nickel-iron magnetic alloy are also affected by the quantity of deoxidizers and contained gas. So, the author prepared the subject alloy by vacuum melting to make the impurity i.e., hydrogen, oxygen, manganese etc. decrease and investigated the resulting characteristic properties. As for a 50% nickel-iron magnetic alloy, heavily cold-rolled and having a rectangular hysteresis loop, the coercive force of the vacuum-melted specimen is much smaller than that melted in air. While we looked through the refining time in melting of this alloy, we have found out the fact that the longer was the time, the better were the properties. Collecting four samples of which the refining time were 20(A), 75(B), 180(C), 300(C) minutes respectively, the properties of B and C are not much different but consideravely better than in A. But it is noted that the properties of D are superior to those of the other specimens.
