The Difference Between The Neodymium And Ferrite Countersunk Magnet

Ferrite countersunk magnet is a metal oxide with ferromagnetism. In terms of electrical characteristics, the resistivity of ferrite is much larger than that of metal and alloy, and it has better dielectric properties. The magnetic properties of ferrites also show high permeability at high frequencies. Therefore, ferrite has become a non-metallic magnetic material widely used in the field of high-frequency weak current. A non-metallic magnetic material is a composite oxide (or ferrite) of ferric oxide and one or more metal oxides. The magnetic force is usually 800-1000 Gauss, which is often used for loudspeaker box, speakers, and other instruments. 

The advantages of neodymium countersunk magnet are that it is cost-effective and has good mechanical properties. The deficiencies are the low-temperature point of Curie, poor temperature characteristics and easy to powder corrosion. It is necessary to improve the chemical composition and surface treatment to achieve the practical application. Neodymium is the third generation of rare earth permanent magnetic materials. With the characteristics of small volume, lightweight, and strong magnetic properties, it is the most cost-effective at present and known as the king of the magnetic field in the magnetic field. The advantages of high energy density make neodymium permanent magnetic materials widely used in modern industry and electronic technology. Under the condition of bare magnetism, the magnetic force can reach about 3500 Gauss. The core technology of neodymium magnet industry is mainly reflected in the manufacturing process, which is embodied in the uniformity, consistency, processing quality and coating quality of the products.
