Permanent Rare Earth NdFeB Neodymium Block Magnet
NdFeB magnets can be used at temperatures down to -200 degrees C (it can be used in liquid nitrogen). NdFeB magnets can be used at temperatures up to +80 degrees C for most of the standard grades of NdFeB (N50, N52 versions are rated to +60 degrees C) and can be used at temperatures getting up towards +230 degrees C when using the higher temperature rated grades of NdFeB. The magnet grade choice, magnet shape, magnetic circuit and the environmental conditions all affect the actual magnetic performance from a NdFeB magnet. Our technical support can help you specify the best NdFeB magnet for your requirements and we can then supply that magnet.
NdFeB magnets are readily available and the NdFeB and SmCo magnets are produced in several hundreds of tonnes each year globally.
Nxx – up to +80 degrees C maximum
NxxM – up to +100 degrees C maximum
NxxH – up to +120 degrees C maximum
NxxSH – up to +150 degrees C maximum
NxxUH – up to +180 degrees C maximum
NxxEH – up to +200 degrees C maximum
