    1. Meterial:  Neodymium/NdFeB/the rare earth Magnet    2. Technology: Utilizes new Sintered NdFeB Magnet techniques and equipment such as strip casting, HDDR technology   3. Magnetic properties:  High coercive force, the max operation temp is up to 200 degree centigrade or 380 curie temperature;   4. Grades: N33-N52, 33M-48M, 33H-48H, 30SH-45SH, 30UH-38UH and 30EH-35EH;   5. Shapes and sizes:  Various kinds or according to customers' request .   6. Coatings: Ni, Zn, Phosphating, epoxy and so on;   7. Motor magnet Applications:  Widely used in different applications, such as sensors, motors, rotors, wind turbines/wind generators, loudspeakers, magnetic hooks, magnetic holder, filters automobiles and so on.   8. Quality Control : Our QC team consistsof more than 12 professional people to ensure 100% products high quality .   9. Extremer Power Warming : These magnets are dangerous !  If your fingers are trapped between two they will cut your skin  . Please be note they should  only be handled with great care .   10. Transportation :  All available shipping ways could be applied ,by courier ,by air or by sea . Appinted shipping company or our own forwarders all could be used in shipment .  Full-way tracking the cargos for you before th good arrival .   Our factory can also manufacture various sizes of other NdFeB magnets, according to the customer's specification      More pictures       Product Advantages High Performance: The high performance YY-MAG can reach: N54, 52M, 50H, 48SH, 42UH,  38EH, 33AH, etc.  High Consistency: The Cpk of Remanence (Br) and Intrinsic Coercive Force (Hcj) are much higher than 1.67. The consistency of the surface magnetic field and magnetic flux can be controlled at +/-1%. High Working Temperature: The magnets of  YY-MAG can satisfy the working temperature requirements with excellent temperature resistance. The AH series with 40 kOe super-high coercive force can replace Smco magnets in most applications. High Anti-Corrosion: The perfect coating of YY-MAG can meet many anti-corrosion requirements. The salt spray test and humidity heat test of the high anti-corrosion coating Nickel+Copper+Epoxy is typically more than 1000 hours.   Our Services 1.      Quick response: we commit to give you immediate detailed quotations with instructions and product material. And customize your required product in the shortest time. 2. High-quality products and favorable price: we reduce material costs through purchase large quantitative of raw materials and other measures from manufacturers directly, which ensure good quality and favorable price of our products, and we share our profit with customers. 3. Closed service: Big or long-term cooperation customers can become our VIP customers and enjoy more competitive prices and VIP service.     Packaging & Shipping 1. 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.   Shipping: Express (TNT, DHL, FedEx, UPS, etc), Air, Ocean.
a: The weight is under 40Kgs, we recommend to send them in shielding boxes to you by Express.
b: The weight is between 40Kgs-100Kgs, it can be sent by Express or Air.
c: The weight is over 100Kgs, we recommend to send them by Ocean.   FAQ: 1: What is normal dimension of your products? All magnets are customized. 2. What information do I need to supply when I have a inquiry? If you have any inquiry, please kindly advise the following items: a. Dimensions or drawing with tolerances. b. Material grade or magnetic properties.
c. Magnetic direction.
