Ningbo Hongji Magnetic Material Co., Ltd.  

Product Name: High Quality Permanent Cow Magnetic Material Component Cylinder Ferrite Magnet Model NO.: Y10T, Y20, Y25, Y30, Y30BH, Y35, etc. Coating: Customized Shape: Customized Application: Speaker Magnet, Industrial Magnet, Jewelry Magnet, Motor Magnet, Customized Type: Permanent Composite: Ferrite Magnet Certification: RoHS, CE Export Markets: Global Delivery: 3-25days Performance: Customized Trademark: HJ Transport Package: Cartons Specification: RoHS Origin: China HS Code: 8505190090 Product Description The cow magnet is mainly used for dairy farm.The principle is when the cow eating into the materials such as iron nails, iron slag,will pose a great threat to the cow.If you use this magnet, the materials such as iron nails, iron slag,all of them will be sucked by this magnet , thus protecting the cattle stomach.And eat this product, without any side effects.A cow just needs one cow magnet, can be life-long protection.Ferrite magnets are produced from Strontium or Barium, and are a low cost alternative to other magnetic materials such as AlNiCO and other alloys. However, they offer lower energy levels (Br) and are brittle in nature. They can operate up at relatively high temperatures, and offer fairly good resistance to corrosion.We have an assortment of stock ferrites in various shapes and sizes in ceramic 1, 5 and 8 grades.Features:1) Cheapest magnet material2) Good anti-corrosion performance, no surface treatment needed.3) Excellent temperature stability4) Best choice for industrial application5) All shapes can be customized6) Compact crystal7) provide isotropic and anisotrpic1. 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.
