Difference between Ferrite Magnets and Neodymium Strong Magnets

Ferrite magnet is a kind of metal oxide with ferromagnetism. As far as electrical properties are concerned, the resistivity of ferrite is much larger than that of metal and alloy magnetic materials, and it also has higher dielectric properties. The magnetic properties of ferrites also show high permeability at high frequencies. Therefore, ferrite has become a widely used non-metallic magnetic material in the field of high frequency and weak current. It belongs to non-metallic magnetic materials and is a composite oxide (or orthoferrite) of iron oxide with one or more other metal oxides. The magnetic force is usually 800-1000 Gauss, which is often used in speakers, loudspeakers and other instruments.

The advantages of neodymium strong magnets are high costing performance and good mechanical properties. Disadvantages of neodymium strong magnets are low Curie temperature point, poor temperature characteristics and easy to be powdered and corroded. It must be improved by adjusting its chemical composition and adopting surface treatment methods to meet the requirements of practical application. NdFeB belongs to the third generation of rare earth permanent magnets. It has the characteristics of small size, lightweight and strong magnetism. At present, neodymium strong magnets are the magnet in / for the best performance-price ratio and are known as the king of magnets in the field of magnetics. The advantages of high energy density make neodymium strong magnets widely used in modern industry and electronic technology. In the bare magnetic state, the magnetic force can reach about 3500 Gauss.
