Product Name: Wafer Ring Permanent Sintered Ferrite Magnet with High Quality Model NO.: Y10T, Y20, Y25, Y30, Y30BH, Y35, etc. Coating: Customized Shape: Wafer Magnet Application: Speaker Magnet, Industrial Magnet, Jewelry Magnet, Motor Magnet, Daily Supplies Magnetocrystalline Anisotropy: Customized Type: Permanent Certification: RoHS, CE Delivery: 3-25days Export Market: Global Performance: Customized Trademark: HJ Transport Package: Standard Export Carton Specification: ROHS SGS Origin: China HS Code: 8505190090 Product Description The elements of Ferrite(Ceramic)magnet are ferricoxide barium strontium. Ferrite has higher coercive force and higher resistance to be demagnetized and oxidized than other non-rare earth permanent magnets.It is widely used from motors and loudspeakers to toys and craft etc.1. Material: SrO, BaO, Fe2O3.2. Grade: Y10T, Y20, Y25, Y30, Y30BH, Y35, etc.3. Size and Shape: Cylindrical,Arc, Segment, Block, Ring, and up to customer's request.4.Application: Widely used in ammeter, audio, phone, TV, dynamo, Motors, Meters, Speakers, Sensors, Medical Machine products, Magnetic Sport products, etc.5.Advantage:1) Low cost, high energy.2) Good anti-corrosion performance, no surface treatment needed.3) Excellent temperature stability.4) provide isotropic and anisotropic.5) Good electrical insulation, excellent demagnetization resistance6) High coercivity, high resistance, long-term stability, economic price7) Best choice for industrial application.Magnetic material is not standard product,so you can provide details information to us to make it.1.Choose the product grade you need.MaterialIso/AnisotropicRemanenceCoercivityIntrinsic CoercivityMax Energy productBr(mT)Br(Gs)bHc(KA/m)bHc(Oe)iHc(KA/m)iHc(Oe)(BH)max(KJ/m 3 )(BH)max(MGOe)Y10Tc1Isotropic≥200≥2000≥125≥1600≥210≥2600≥6.5≥0.8Y20Anisotropic≥360≥3600≥135≥1700≥140≥1760≥20.0≥2.5Y25Anisotropic≥380≥3800≥144≥1800≥150≥1880≥24.0≥3.0Y30c5Anisotropic≥390≥3900≥184≥2300≥188≥2350≥27.6≥3.4Y30BHc8Anisotropic≥390≥3900≥240≥3000≥256≥3200≥27.6≥3.4Y35c11Anisotropic≥410≥4100≥208≥2600≥212≥2660≥30.4≥3.82.Magnetic direction3.No Coating or Special Coating4.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.
