I am a graduate student at the University of Florida working on a magnetic detection project. I would like to use Mu-metal shielding but am concerned about the curie temperature as I will be exposing it to temperatures as high as 150-200 C. Could you please provide me with any information about the magnetic shielding properties of mu-metal at these temperatures. Thank you
Nickolas
Dear Sir,
The Curie temperature in mu metal varies between a temperature range of 390-450 degrees centigrade, dependant on the chemical composition of the “brand” of the alloy. In the temperature range in question, (150-200 Deg C) mu metal will function normally without any derogatory effect, however we would not, as a general rule recommend usage above 300 Deg C.
Please feel free to contact me if you require any further information
Kind Regards,
