Silicon iron bars

Silicon iron bars

Silicon iron bars

I'm looking for a source for a few 1/4" round bars of free cutting 2.5% silicon iron, something equivalent to Carpenter silicon iron BFM.  Carpenter doesn't have any.  Bigger bars would be OK.

RE: Silicon iron bars

Try Scientific Alloys.

Thanks.  In the end, Carpenter managed to cough up a couple of 3/8" bars we can use.

RE: Silicon iron bars

Who did you talk to at Carpenter?!?!?!??!?! I can never get any material out of them.

I have people.

Magival is not silicon iron.  They are "solenoid quality 430FR" similar to ASTM A838 ferritic stainless.  They do contain silicon but also way too much chromium & other elements for my requirements.

RE: Silicon iron bars

I said"click" on Magival and , on the right side of screen you can find "silicon iron alloy" and other subjects.
Magival is the name of a  group regarding the  soft magnetic grades ( include Fe-Si alloy) of Valbruna and  where you can find free machined stainless steel, not free machined stainless steel, Silicon - Iron ASTM 867 ( different grades with S and P , simple Silicon Iron and so on )
Finally,  the brand FeSi3P is what you are searching.

Found it, thanks.  Could they lay that site out much worse?  They stick a material document created 8 years ago under "news" instead of where all the other materials are.   

RE: Silicon iron bars

dgallup,
you are right : the maintenance is a little bit poor or nobody is so kind to inform Vallbruna stainless  about this inaccurancy or others ones ( as, for instance , 0,8Tesla = 80.000 gauss instead of 8.000 ).
However, it is  a venial sin.
Nevertheless, I suggest to require if they have some (few) bars of grade that you are looking for.
I know that sometime they had also supplied few quantity or some barsfor trials orders.
Good luck !

We got enough material from Carpenter for my immediate needs but I sent Valbruna's info to our purchasing department because we are always looking for alternate suppliers.
