Product Description

High Permeability Soft Magnetic Alloy

Soft magnetic materials are utilized in two key areas - energy conversion and information processing. In the power industry, these materials are primarily used in high magnetic fields that have a high magnetic induction and low core loss of the alloy. On the other hand, in the electronics industry, these materials are mainly used in low or medium alloys that have a high magnetic permeability and low coercive force.

 

However, soft magnetic materials are not without their drawbacks. Due to the alternating magnetic eddy currents that are induced inside the material, there is a resultant loss. The smaller the resistance of the alloy, the greater the thickness, and the higher the frequency of the alternating magnetic field, the greater the eddy current losses and the more reduced the magnetic field becomes. To combat this issue, the material must be made thinner into a sheet or tape and then coated with an insulating layer. Alternatively, certain methods can be used to form an oxide insulating layer on the surface of the alloy. One commonly used coating for this purpose is magnesium oxide electrophoresis.

 

Iron-nickel alloys are often used in alternating magnetic fields, mainly for yoke iron, relays, small power transformers, and magnetically shielded components. Soft magnetic materials play a crucial role in energy conversion and information processing, making them an essential component in various industries.

 

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.
