Magnetic ring - Import export

Silicon nitride magnetic rings are mainly used to protect high voltage electrodes and are widely used in the photovoltaic industry.Heat shields and magnetic rings, as well as ceramic rings, are collectively referred to as electrode shields.Silicon nitride electrode protection cover mainly uses silicon nitride insulation, heat resistance and corrosion resistance.Compared with the protective cover of quartz and alumina which is still in use today, the service life of the silicon nitride electrode shield is more than 10 times, and it will not be electrically broken down during use, and will not be heated, nor will it be heated. Will be eroded away. Due to its own stability, in the use of photovoltaic reduction furnaces, the collapse rate of non-human factors is greatly reduced. Silicon Nitride (Si3N4) Characteristics: 1 Good thermal shock resistance 2 Creep resistance 3 Low density 4 High fracture toughness 5 High hardness and wear resistance 6 Electrical resistivity

Applications: •Magnetic rollers for copier and laser printer •Permanent motor magnets (rotors & other components) •Magnetic rings for aerodynamic component •Color Monitor/TV purity convergence magnet •Binders: PA6, PA12, PPS Characteristics •Binders: PA6, PA12, PPS •Can be magnetized in any direction, suitable for the radial or axial(face) multi-polar magnetized magnet. •One time forming the complex shape. •Forming the shape with the shaft or bushing one time to reduce assembly processes and improve assembly accuracy. •No surface treatment.

Features: Made of ground sintered SmCo magnet Powder is mixed with resin and molded like NdFeB bonded magnet No need to be coated because it is difficult to erode and oxidize High-BH (maximum) High-Br and Hc with high-operating temperature, low-temperature coefficient, counter-demagnetization, decay resistance Main products cover SmCo5 and Sm2Co17 magnets, samarium cobalt powder, various assemblies and more OEM orders are welcomed Applications: Widely used in motors, watches, transducers, instruments, positional detectors, generators, radars and more High quality, competitive price, best service
