Rare Earth Neodymium or Ceramic-8 Magnetic Head Pulleys

Magnetic Head PulleysIPES International’s magnetic pulleys are used in conveyor systems to remove ferrous metal from the product flow. They’re offered in two types: Rare Earth Neodymium or Ceramic-8.

Ceramic magnets came into existence in the 1950s, and in the 1980s neodymium magnets were invented. So what’s the difference?

Ceramic magnets are made out of powdered barium or strontium ferrite formed into the shape of the magnet and baked on. Neodymium magnets are made from pure metal alloys– neodymium, iron and boron. These metal alloys can sometimes be powdered, mixed and pressed together, and/or combined to be molten, cooling into solidity.

Ceramic magnets are stronger than natural stone magnets and they’re easy to magnetize as well. They have a high intrinsic coercive force. Since they’re very resistant to corrosion and demagnetization by outside magnetic fields, they’re quite popular for many uses. Neodymium magnets, meanwhile, are even stronger than ceramics. Indeed, they are the most powerful of all permanent magnets, able to lift more than any other type of magnet of similar size.

Neodymium magnets work best for applications where high magnetic fields are required. If you have very powerful turbines and generators, use neodymium. You’ll find that neodymium magnets are not only very resistant to demagnetization, but also high energy for their size and good in ambient temperature.

The most common grades of ceramic are 1, 5 and 8. IPES offers Ceramic-8 magnets; Grade 8 is the strongest ceramic material available.
