Product Name: Ferrite Magnet for Motor / Hard Ferrite /Ferrite Integated Rotor for Motor /Permanent Ferrite Model NO.: ferrite magnet Shape: Ring Application: Speaker Magnet, Industrial Magnet, Jewelry Magnet, Solenoid, Motor Magnet Magnetocrystalline Anisotropy: Anisotropic Magnet Type: Permanent Certification: UL, RoHS, CE, ISO9001, ISO14001 Size: Customized Export Markets: Global Trademark: SPN Transport Package: CTN/Pallet Origin: China HS Code: 8505119000 Product Description I.Ferriteanisotropicsintered magneticringsAnisotropic sintered ferrite magnets have higher magnetic properties compare with isotropic ferrite magnet. However, this type of magnets can only be magnetized along the preferred direction;the sintered Ferrite has an excellent resistance to demagnetization.The Polar Anisotropic Ferrite Ring Magnets are the magnets with multipoles in ring shape. They have become the key component of stepping motors which are widely used in computer peripheral and consumer electronics, such as washing machine,different types of pumps, printer and digital -camera,etc.II.Features:The products of the company are with precision size, stable performance, excellent quality products; the diameter is in the range of 10mm-80mm, from 2 poles to 48 poles with variety of specifications,we can supply sine wave, trapezoidal wave, square wave and other magnetizing waveform. High performance of the products and the surface magnetic flux density can reach from 1200 GS to 2100GS.According to customer's request, good quality with competitive price and best delivery time, one station service.Guarantee the best price based on the same quality.Product NameFerrite Magnetic RingDescriptionFerrite anisotropic sintered multipole ringMaterialThe low cost magnetic material, main contents ferric oxide, barium and strontiumWorking temperature250 degreeManet ShapeRound , CylindricalDimension scope¢(12-70)*¢(7-35)*40FeaturesA low cost alternative to other magnetic materials, good resistance to corrosion & demagnetization.ApplictionsDC brushlessmotors, Precision motors,Louder speakers, Magnetic Separators, Automotive Sensors, etcPackingCarton or pallets or as per customer's requirementShippingBy sea, By air, by Express wayIII. Manufacturing Process :1.Two Manufacturing process :Dry process can produce isotropic & anisotropic magnets, tool can be changed and developed easily.By wet process, only anisotropic magnets can be produced, it is complicated to change the tool and the tooling charge is much higher.2.Magnetization :Isotropic ferrite magnets are not oriented and can be magnetized in any direction. Anisotropic ferrite magnets are different, they are all oriented in the manufacturing direction, and should be magnetized in the direction of orientation.V.
