Ferrite magnets are popular because of their stability, affordable price and short delivery time. In addition, they have excellent magnetic properties such as a high operating temperature up to 300 °C.
Neodymium magnets - NdFeB
Choose neodymium magnets if you need a permanent magnet that is small, lightweight and super strong. This extraordinarily powerful magnet is known under the brand name Neoflux®.
They have the highest available magnetic energy density, with a BHmax value of 30 MGOe to 52 MGOe.
Samarium cobalt magnets - SmCo
Samarium cobalt magnets have a high magnetic force of up to 30 MGOe and excellent stable magnetic properties over a wide temperature range. They also have excellent resistance to demagnetization and corrosion. They have a working temperature of up to 350 ⁰C.
AlNiCo is a magnetic alloy with excellent thermal performance and the ability to demagnetize in a controlled manner. In addition to these properties, it is chemically inert and resistant to corrosion. Most AlNiCo magnets are cast and can be made in complex shapes.
