Neodymium Magnets are made from an alloy containing, amongst others, the elements Neodymium, Iron and Boron (NdFeB). It is the strongest type of magnet and manufactured in a wide range of shapes, sizes and grades and different coatings/finishes.1.Grade cover N35-N52, N30M-N50M, N30H-N48H, N30SH-N45SH, N28UH-N40UH, N28EH-N38EH.2.Size and Shape:D3--D280mm(round)Cylindrical, Ring, Square, Holed Square, Watt, Arch, or Customized.3.Coating: Nickel,Nickel copper nickel,Zinc, Golden, Black epoxy, Grey epoxy, Phosphating and so on.4.Direction of magnetisation:Through the thickness or through the diameter.a. Magnetization thickness B. Axial magnetization C. Symmetric magnetization D. Multipole magnetization E. Radial magnetization. Special requirements for custom magnetization5.Application of NdFeB magnet: Toys, Package, Printer, Switchboard, Phone, Vcoil motors (VCM's) in hard disk drives, High performance(maglev, linear and rotary) motors, Bearings, Eddy-current brakes, Brushless DC motors, Magnetic separation, Magnetic resonance imaging, Sensors, Loudspeakers, Jewelry industry and etc.6.Advantage1)Excellent temperature stability2)Small size and light weight3)Strong magnetism4)Relatively high energies characterize5)High performance-to-price ratio,widely usedMagnetic material is not standard product,so you can provide details information to us to make it.1.Choose the product grade you need.GradesN35-N52N35M-N50MN35H-N48HN35SH-N45SHN30UH-N40UHN30EH-N38EHW T80°C/60°C100°C 120°C150°C180°C200°C- The grades like N48-N52 could meet your requirement on strong power- Standard one like N35 or N38 is okay for your normal applications- If you have requirement on the working temperature, please note it.2.Magnetic direction3.Choose the coating you want.4.Choosethe product sizeyou need.5.Packaging&Shipping1)By Sea: As the magnets have strong attraction and we will use the spacer to apart the magnets each other in case people will be hurt when take it out. Then, they will be packed in a white box of pieces each, several boxes to a carton. (Detailed package quantity should be made upon the real products)2) By Air: If the goods will be shipped by air, all the magnetic should be degaussed and we will use Iron sheet to shield.6.Payment7.Frequently asked questions1) What is the normal size of your product? All magnets are custom made.2) What information do I need to provide when I ask? If you have any enquiries, please inform us of the following:a.Size or drawing with tolerances.b.Grade of material or magnetism.c.magnetic directiond.Surface coating (if necessary)e.Quantity and delivery conditions.3) How long will you give me an answer? We'll get back to you in 24 hours.4) What's the price? We will try our best to satisfy you.5) Can I have a sample? Yes, we have stock in stock. We can help you get the sample as soon as possible.6) How long will you deliver samples and bulk orders? If we have stok, we can send it in 3 days. If we do not have stock, the production time of samples is 5-10 days and the time of bulk order is 15-25 days.8.Our Factory Profile9.Grade Instructions/ Sintered NdFeB MagnetGrade Residual Induction (Br)Coercive Force (Hcb)Intrinsic Coercive Force (Hcj)Max Energy Product (BH)maxTemp.
