MnCu Manganese Copper Ferrite?
MnCu Manganese Copper Ferrite?
(OP)
Does anybody know a manufcturer of Manganese Copper Ferrites? I am looking for a ferrite that has a low curie temperature and have found a paper that shows various MnCu ferrites with curie temps between 50-100 degC. They seem to have been used i nthe 1960s and 70s but were surpassed by other materials. Does anyone still have the ability to produce them?
Many thanks
Many thanks





RE: MnCu Manganese Copper Ferrite?
are you hoping to exploit the curie temp, specifically? I'm certain they can still be produced, and may still be produced, I can find out more in a day or so.
What are you trying to accomplish with these magnets?
I ask because other magnets might be able to do it. or a thermostat?
RE: MnCu Manganese Copper Ferrite?
MnCu ferrites are a bit of an off the wall suggestion for my research and I have many other materials that I will be looking at, it's just that these seemed quite promising and didn't want to leave them out of the study.
There are plenty of companies manufacturing other ferrites but some are really just distributors and I only need a small quantity.
If you do know of anywhere that would be able to make some I would be very grateful.

That said, any magnetics you could get out of what you've determined to be obsolete magnets can be provided, and with better uniformity, by newer compositions.
What specifically about MnCu ferrites is of interest?

I should hear back whether the aforementioned branch has ever dealt in mncu ferrites. Failing that, I know of two alternatives that may be worth investigating.

As for fitting a magnet into your system, could a small electromagnet work into the design?
Also, to clarify, I presume you realize that hitting the curie temp is a one-way trip? As in, the mncu ferrite would remain demagnetized upon cooling down, thus rendering the low temperature operation of half your sensor suite useless after seeing temps above 50°C
