Need a list of core materials and their permeabilities

In summary, core materials are soft magnetic materials used in the construction and manufacturing of various products. Permeability is a measure of a material's ability to support the formation of a magnetic field within itself. It is important to know the permeability of core materials in designing and optimizing electronic and electrical devices. Some examples of core materials and their permeabilities include iron, nickel, cobalt, and their alloys, as well as soft ferrites. The permeability of core materials is typically measured using a permeameter, which applies a magnetic field and measures the resulting magnetic flux density.

Go to the manufacturer's websites, and look at their core material datasheets.

Here's a link to the TDK pages, for example:

mag-inc and mecrometals will cover a broad range. You'll still need someone that sells laminates.
 

FAQ: Need a list of core materials and their permeabilities

What are core materials?

Core materials are materials used in the construction or manufacturing of various products, such as electronic devices, transformers, and motors. They are typically soft magnetic materials that have high permeability, which allows them to efficiently conduct magnetic flux.

What is permeability?

Permeability is a measure of a material's ability to support the formation of a magnetic field within itself. It is a property that determines how easily a material can be magnetized and how strong the resulting magnetic field will be.

Why is it important to know the permeability of core materials?

Knowing the permeability of core materials is important in designing and optimizing various electronic and electrical devices. The permeability directly affects the efficiency and performance of these devices, so selecting the right core material with the desired permeability is crucial.

What are some examples of core materials and their permeabilities?

Some common core materials include iron, nickel, cobalt, and their alloys. The permeability of these materials varies depending on the composition and processing, but they typically fall in the range of 1000 to 5000. Soft ferrites, such as manganese-zinc and nickel-zinc ferrites, also have high permeabilities in the range of 100 to 1000.

How is the permeability of core materials measured?

The permeability of core materials is typically measured using a permeameter, which applies a magnetic field to the material and measures the resulting magnetic flux density. The ratio of the magnetic flux density to the applied magnetic field is the permeability of the material. This process can be done with either DC or AC magnetic fields.
