本文是关于具有高饱和磁化强度、低矫顽力的高抗张强度和高疲劳强度的作为机器磁路结构部件的磁性弹簧用的铁、铬、镍合金的制造方法。由于最近电子交换机等各种通信机器的发展,而要求一种兼备磁特性(软磁特性)和机械特性的弹簧材料。本文制造的合金是作为电子交换机的闩锁开关的“保持型的指状材料”。所要求特 This is a method of manufacturing iron, chromium, and nickel alloys for magnetic springs as machine magnetic circuit components having high saturation magnetization, high tensile strength at low coercivity, and high fatigue strength. Due to the recent development of various communication machines such as electronic exchanges, a spring material that combines both magnetic properties (soft magnetic properties) and mechanical properties is demanded. The alloy made in this article is a “hold-type finger” that acts as a latch switch for electronic switches. Required special
