super magnets
Super magnets are ceramic material pressed from NdFeB
powder (or SmCo powder). They are the most powerful
magnet type known and have a 10-fold effect compared
to basic ferrite magnets. Normally they endure temperatures
up to 80 °C but there are also magnets that endure
up to 200°C. The NdFeB alloy is not corrosion
resistant so the magnets are almost always coated
with for example zinc or nickel. All magnets in our
stock are coated. The SmCo resists corrosion far better
than NdFeB and also endures temperatures up to 250
°C. Super magnets are also available combined
to plastic; these are only half as effective as ceramic
magnets.
Super magnets are most commonly used in electronic
industry where great power output combined with small
size is needed.
