1J80 soft magnetic alloy is a special material with high saturation magnetic induction strength. Saturation magnetic induction intensity is the large magnetic field strength that magnetic materials can withstand at a certain temperature and magnetic field strength, and is one of the important parameters to measure the performance of magnetic materials. 1J80 soft magnetic alloy has high saturation magnetic induction strength and can adapt to strong magnetic field environment, so it is widely used in some strong magnetic field environments. Another characteristic of 1J80 soft magnetic alloy is low coercivity, that is, the hysteresis loop slope is small. This means that the material is more likely to be magnetized when the external magnetic field changes, and is easier to be controlled and regulated by the external magnetic field. Therefore, 1J80 soft magnetic alloy has good soft magnetic properties and is widely used in electric power, electronics, communications and other fields. In addition, 1J80 soft magnetic alloy has good corrosion resistance and high temperature stability. It retains stable magnetic properties over a wide range of temperatures and is highly resistant to the effects of environmental factors such as humidity and air pollution. Therefore, 1J80 soft magnetic alloy has been widely used in some special application fields, such as marine environment, chemical equipment, etc. As a high-performance magnetic material, 1J80 soft magnetic alloy has the advantages of high saturation magnetic induction strength, low coercivity, good corrosion resistance and high temperature stability. These characteristics make 1J80 soft magnetic alloy widely used in many fields and has good application prospects.
