Products Introduction:Known as third generation of Rare Earth magnets, Neodymium Iron Boron (NdFeB) magnets are the most powerful and advanced commercialized permanent magnet today. Since they are made from Neodymium, one of the most plentiful rare earth elements, and inexpensive iron, NdFeB magnets offer the best value in cost and performance.NdFeB magnets are available in both sintered and bonded forms. Sintered NdFeB offers the highest magnetic properties (28 MGOe to 50 MGOe) while Bonded NdFeB offers lower energy properties. Although bonded magnets do not possess magnetic properties as advanced as those of sintered magnets, they can be made in shapes and sizes that are difficult to achieve with sintering.A variety of coatings can be applied to the magnets' surface to overcome the principle drawback of neodymium-based magnets, their tendency to corrode easily.Products Details:Product name:Big Block NdFeB MagnetShape:Block ( Disc, Block, Ring, Countersunk, Segment, Trapezoid, Irregular shapes ?are available, Customized shapes for Sintered NdFeB ?Magnet are also available)Direction of magnetisation:Through the thickness or through the diameterType of coating:Nickel, Ni-Cu-Ni, Zn, Gold, Silver, Copper, EpoxyGrade:N35-N52; N35M-N50M; N35H-N48H; N35SH-N45SH;N30UH-N40UH; N30EH-N38EHTolerance in size:+/-0.1 mmApplications of Neodymium Magnets:AC Motors, DC Motors, servo motors, step motorsComputer rigid disc drivesMagnetic SeparatorsMagnetic resonance imagingSpeakers & earphonesMedical care machinesPackaging & Shipping?L35*27*14cm cartons with foam well protected, or according to customer's request.?Packages for sea or air shipping are both available for Big Block NdFeB Magneta: the weight is under 40Kg,we will choose DHL or UPS with shielding box for you;b: the weight is over 100Kg,we will choose sea shipping for you;c: the weight is between 40Kg-100Kg per you request;FAQ1.Q: Are you a trading company or manufacturer ?A: Our company is a professional manufacturer of magnets and magnetic assemblies .2.Q: What information do I need to supply when I have an inquiry?A: If you have any inquiry, please kindly advise the following items:Dimensions, sizes, shape and drawing with tolerances.Material grade or magnetic properties.Magnetic direction, quantity.
