Manufacturers of ndfeb magnet ndfeb its advantage is with good mechanical properties, high cost performance. Its drawback is that low Curie point temperature, temperature characteristic is poor, and is easy to be pulverization corrosion, must through the adjust its chemical composition and take surface treatment methods to improve, to achieve the requirements of practical application. Ferrite is a ferromagnetic metal oxide. In terms of electrical characteristics, ferrite have higher dielectric properties, its resistivity is much bigger than metal, alloy magnetic materials. Ferrite magnetic can also performance in high frequency with high magnetic permeability. Therefore, ferrite has become a high-frequency weak current widely used in the field of magnetic material, not of metal. Ndfeb belongs to the third generation of rare earth permanent magnet materials with the characteristics of small volume, light weight and strong magnetic, is currently the best price-performance magnets, the magnetic field is known as the king of magnetic. The advantages of high energy density of nd-fe-b materials in modern industry and obtained widespread application in electronic technology. Under the conditions of bare magnetic, magnetic force can reach about 3500 gauss. Ferrite or as a ferrite magnetic porcelain, is belong to nonmetallic magnetic materials, magnetic ferric oxide and other one or more metal oxide compound oxide ( Or is ferrite) 。 Magnetic usually is 800 - 1000 gauss, often used in the speakers, speakers and other devices. Ndfeb magnets and the difference between the ferrite magnet mainly include the following: 1. Ferrite magnet performance ndfeb. 2. Price, the price of the ferrite is much cheaper than the ndfeb magnet. 3. Ndfeb magnet heat resistance is very good, ordinary ndfeb usually only 80 degrees, more than the working temperature of demagnetization will happen. 4. Stability of ferrite is very good, it itself is oxide, is stable, ndfeb alloy, and its easy oxidation, coating protection must do. Shenzhen star create magnetic industry company, the company focused on magnetic materials & amp; Components manufacturing and solutions. Reasonable price, reliable quality, punctual delivery, can processing production ndfeb magnet circle, square, tile shape, countersunk head hole, hole, grinding arc, steps, reducer, tapered, ladder shaped, bread shaped magnets.
