The difference between amorphous and ferrite cores

May 22, 2024

Amorphous magnetic core and ferrite magnetic core are two kinds of magnetic core materials commonly used in electronic components, which can realize power conversion and energy storage. However, in practical applications, we need to choose the core material suitable for ourselves, so we need to understand the difference between them.

1. Basic concept between amorphous core and ferrite core

Amorphous core (Amorphous magnetic core) is a kind of magnetic core material made of amorphous metal strips, which is prepared by powder metallurgy. Ferrite core is an iron core type magnetic material composed of iron, oxygen and other elements, and its preparation method is diversified, which can be used chemical method or physical method.

2. Performance comparison of amorphous magnetic core and ferrite magnetic core

The permeability, saturation magnetization and loss characteristics of amorphous magnetic core and ferrite magnetic core show different degrees of differences, so it is necessary to select materials according to specific conditions in practical applications.

• Permeability: The permeability of the ferrite core is higher than that of the amorphous core.

• Magnetic saturation magnetization: The saturation magnetization of the ferrite core is higher than that of the amorphous core.

• Loss characteristics: The loss of amorphous core is less than the loss of ferrite core.

3. Application range of amorphous core and ferrite core

The application range of amorphous magnetic core and ferrite magnetic core is limited to each other.

• Application of amorphous magnetic core: power electronics, communication electronics, computers, etc.

• Ferrite core applications: audio and video equipment, consumer electronics, household appliances, etc.
