The difference of neodymium iron boron magnet and ferrite magnets:
Characteristics of neodymium iron boron magnet:
1, the performance to price ratio is high, with good mechanical properties;
2, the shortage is that the Curie temperature point in low temperature characteristic, difference, and easy powder corrosion, must surface treatment method by adjusting the chemical composition and taken to make improvements, in order to meet the requirement of practical application.
3, neodymium iron boron belongs to the third generation rare earth permanent magnetic materials, has the advantages of small volume, light weight and strong magnetism characteristic, is currently the best cost performance magnet in the magnetic field is known as magnetic wang.
4, has the advantages of high energy density of the Nd-Fe-B permanent magnetic materials have been widely used in modern industry and electronic technology.
In 5, bare magnetic state, the magnetic force can reach 3500 around Gauss.
Ferrite magnet is a kind of ferromagnetic metal oxide.
1, electrical properties, resistivity ferrite than metal, alloy magnetic material is much greater, but also has high dielectric properties.
2, the magnetic ferrite can also has a high magnetic permeability in performance at high frequency. Therefore, ferrite has become non metal magnetic material uses high frequency weak electric field widely. Belongs to the non metal magnetic material is composite oxide magnetic ferric oxide and one or more other metal oxides (or ferrite). The magnetic force is usually 800-1000 Gauss, often used in speaker, speakers and other equipment.
