热处理工艺对超级纯铁磁性的影响工程纯铁可以用来制造各种电磁铁的磁芯、极靴、磁屏蔽，制造继电器的铁芯或磁路零件，也用于制造测量仪表中的磁路零件和电话听筒的震动膜。纯铁按性能差异又可分为普通级、高级、特级和超级纯铁。航天系统对磁路的要求很高，多采用无磁时... Effect of Heat Treatment Process on the Magnetic Properties of Super Pure Iron Engineering pure iron can be used to make magnetic cores, pole pieces, magnetic shields for relays, iron cores for manufacturing relays, or magnetic circuit components. It is also used to make magnetic circuits in measuring instruments Vibration membrane for parts and telephone handset. Pure iron according to performance differences can be divided into ordinary, advanced, super and pure iron. Aerospace systems on the magnetic circuit requirements are high, and more use of non-magnetic ...
