small magnets round MATERIAL:are composed of neodymium 20%-30%, iron 60%, boron and a few transition metals. Attributes of Neodymium Very high resistance to demagnetization High energy for size Good in ambient temperature Moderately priced Material is corrosive and should be coated for long term maximum energy output Low working temperature for heat applications, but higher levels of heat resistance materials are being introduced periodically. Product Description small magnets round 1.material : sintered NdFeN magnets 2.grade: N35-N52, N38M-N50M, N35H-N48H, N33SH-N44SH, N30UH-N40UH, N30EH-N35EH, N28AH-N35AH 3.shape: ring, block ,arc.disc and as your requirement 4.size: D30X2mm 5.magnetization direction: thickness, axial, radial 6.surfaceing coating : Zn, Ni. double Ni. Ni+Cuz+Ni ,epoxy and so on A. Advantage a. Chemical Composition: Nd2Fe14B: Neodymium Magnets are hard, brittle and easily corrode; b. Moderate Temperature Stability: Neodymium magnets lose -0.09~-0.13%of Br/°C. Their working stability is under 80°C for low Hcj Neodymium magnets and above 220°C for high Hcj Neodymium magnets; c. Excellet Strength Value: The highest(BH)max reaches up to 51MGO. B.Application memo,toy,lab , sensors, speakers, brushless motor, DC motor, Step motor, wind turbine/wind generator, magntic hooks, magnetic filter, cup magnet, Automobiles, magnetic coupling, magnetic chuch, permanent magnetic lift, and so on. C. the physical properties
Packaging & Shipping small magnets round 's delivery and packing + delivery : 7--- 15 working day + packing : Plastic bag -> Inner box -> Master carton: 29cm x 23cm x 14cm Plywood case (1) air package (2) sea package surface treatment The corrosion resiatance of Ndfeb is considered ad its drawback ,in order to protect the corrosion , it is effective to coatted on its surface , commonly surface trestment of magnet detail ad followed
characterisitics of surface treatment : magnet produce manufacturing small magnets round a. the raw material are burdebed according to Ndfeb . b. the burdeded material are melted at a high temperature to form an alloy ( or stip casting ) in vacuum induction furnace . c.the particles are placed in a magnetic field and pressed into any desired shape . d.the products are heat treated at a temperature of 1000 degress or higher in a sintering furnace. and then aging the magnets to adjust the properties. e.the magnets are tested their magnetic properties . f. the manets are machined to the desired size and shape including surface treatment . g. visual inspection at last.
