Semi-hard magnetic alloy is a kind of functional material with medium magnetic hard properties,which is between soft magnetic and permanent magnetic.For the electrical core equipment components in special scenarios,its importance has become increasingly prominent.The continuous improvement of the performance requirements of semi-hard magnetic alloys has also promoted the development of semi-hard magnetic alloys in the direction of high performance and low cost.Research on new semi-hard magnetic alloys is an increasingly urgent demand in the mar-ket environment.This paper summarizes the different types of semi-hard magnetic alloys,the theory of magnetic properties of semi-hard magnetic alloys,and the trend of developing semi-hard magnetic alloys,in order to provide reference for the follow-up research of semi-hard magnetic alloys.
