High Perm with Low Saturation Material

High Perm with Low Saturation Material

High Perm with Low Saturation Material

(OP)
I'm sure this has probably been answered already, but the search is less than agreeable at the moment.  I've been looking through the datasheets of a wide variety of alloys but am hoping someone here can help speed up my search.  I need a material with a high magnetic permeability but very low saturation level.  

The more permeabile and quicker the material saturates, the better.  Currently I am using Nickel, but there has to be something better out there.

As always, any help is greatly appreciated.

Silicone Steels.  Check out Tempel Steel Company.

RE: High Perm with Low Saturation Material

I think BobM3 meant Silicon Steels, not Silicone...

Razillian: It would be helpful if you could quantify your requirements a little more.  You mentioned you want something better than nickel, but that is still rather vague.

However, I will make one suggestion: Try iron powder mixed with an epoxy binder.  The iron will have high permeability, but because it is "diluted" with the epoxy binder, the magnetization output will be reduced.

RE: High Perm with Low Saturation Material

Ni is the classic for high perm/moderate saturation.  Either Fe powder or a ferrite may be you best option that won't break the bank.

RE: High Perm with Low Saturation Material

when did iron powder acquire high perm!

is this for switching, shielding, or a small signal application

why are you using nickle?
