Vanadium Permendur?

Hello. I was thinking of furthering the research I did for the science fair and I was wondering if there is anywhere to get vanadium permendur for cheap. Am I right in assuming that at high levels of magnetic flux, this is the best alloy to use (has the highest relative permeability). All the other alloys that I've been looking at their permeability drops out dramatically at high levels of flux density.

This is the only site that I've found that sells this kind of thing.


So in a nutshell, does anybody know off the top of their head a place to buy permendur where it doesn't cost $150 per inch? (I'm gonna buy some regardless, but I'd like to know if it gets cheaper)

Or, if a couple guys want to pitch we could a buy a larger section and cut it up to reduce cost.

I'm looking to see if the equation that I have for force on a ferromagnetic projectile from a capacitor-driven solenoid is accurate, and I can't do that without something that has a drastically different magnetic permeability that steel.
