High Permeability Soft Magnetic Alloy

Supply 1J79/1J85/1J87 Permalloy Precision Alloy Wire With Factory Price

Soft magnetic materials are essential components in both the power and electronics industries. In the power industry, these materials are used in high magnetic fields to achieve a high magnetic induction and low core loss. On the other hand, in the electronics industry, soft magnetic materials are mainly used in low or medium magnetic fields, with a high magnetic permeability and low coercive force.

When it comes to high frequencies, thin strips or alloys with higher resistivity are preferred. This is because, in soft magnetic materials, alternating magnetic eddy currents are induced inside the material, resulting in loss. The higher the frequency of the alternating magnetic field, the greater the eddy current losses, and the more the magnetic field is reduced. Therefore, to minimize these losses, the material must be made thinner, usually in the form of a sheet or tape. Additionally, the surface of the material is coated with an insulating layer or an oxide insulating layer is formed on the surface using certain methods. One common method is to use magnesium oxide electrophoresis coating.

In summary, soft magnetic materials are crucial in both the power and electronics industries. Their properties are carefully chosen depending on the application and frequency range. To minimize losses due to eddy currents, the material is made thinner and coated with an insulating layer.

Applications

High sensitivity and small power transformers, magnetic amplifiers, relays, chokes, magnetic heads for magnetic recording devices, magnetic shields, various tape wound cores, cut cores, and laminated cores used in weak magnetic fields.
