  Product Description neodymium magnet cylinder the Sintered Ndfeb Magnets  is the important industrail product to promote technological and  social progress and is mainly composed of  Neodymium, Iron ,boron and other  microelements (Al, Ga, Mo,Co). It is known as " King of magnet".   A. specification 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:    D10x30mm 5.magnetization direction: thickness, axial, radial 6.surfaceing coating : Zn, Ni. double Ni. Ni+Cuz+Ni ,epoxy and so on   B. 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.   C.Application  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.    D. the  physical properties

  neodymium magnet cylinder      Packaging & Shipping   + 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  
 Metallic :
 white zinc , colur zinc , nickle, nickle + nickle , nickle + tin, nickle + copper + nickle , epoxy , passivation
characterisitics of surface treatment :   magnet produce manufacturing process   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.         Company Information   Sunny Fore Magnet  we are factory for magnet, - Various Dimension & shaped : (up to client's demend) -Tolerance: +/-0.05mm - Coating: Ni, NiCuNi, Zn, Au, Ag, epoxy - Quality is pass RoHS(2002/95/EC)  & EN71/3, REACH - Delivery day is about 7-15 days.
