1J79
1J79 alloy is an alloy with high initial permeability, and its consumption is only second to silicon steel sheet and electrical pure iron. Compared with other soft magnetic alloys, these alloys have high permeability and low coercivity under low magnetic field. Some alloys also have rectangular hysteresis loops, or very low residual magnetic induction strength and constant permeability, and have special applications This kind of alloy is the most widely used alloy in magnetic materials. Because it is easy to magnetize and demagnetize, it has small coercivity in weak magnetic field, narrow hysteresis loop and small area. Therefore, it is an indispensable important alloy material in electronics, electric power, aerospace, automatic instruments, meters and other industries.
