Highest saturation magnetization material?
(OP)
What is the material that has the highest saturation magnetization?
For example, which material would have the highest induction magnetization inside the bore of a 1.5 Tesla Magnetic Resonance Imaging apparatus?
Thanks

This somewhat depends on the field strength and temperature. At very high field strengths the highest saturation is at lower Co contents, say about 35% (Fe2Co), this is also true as you go to temperatures lower than room temp.
If you cut or machine a part it will need a good anneal to recover maximum saturation.
Additions of V or Cr help to lower the initial permeability, but lower the saturation.

I just want the highest saturation. I know that FeCo alloys have high saturation but so does pure iron.
Which of pure Fe or FeCo has the highest saturation? Is there another material as good or better? Is there scientific litterature on this?
Thanks

Even high purity Fe has a tough time topping 2T. In high purity form this alloy has been reported at 2.6T.

If 35% cobalt is so good why doesn't anybody make it? 2.6T would be worth a fortune.

That explains why we made our own.

1. Can be hard to get in useful forms. Scientific Alloys is the only distributor I've found that sells it in small volumes in something substantial.
2. It requires a very specific anneal prior to use, and after all machining. Without it, the saturation induction is a fraction of its theoretical.

I just got off the phone with someone from Scientific Alloys in Rhode Island.
He really took the time to understand what I wanted to make and gave me tips on how to manufacture that. In the end he recommended pure iron versus hiperco for its ease of machining.
