Ndfeb neodymium big block magnet with holes The Sintered NdFeB Blocks are widely used in wind generators, meters, sensors, aerospace, automotive, electronics, electro-acoustic, communications, instrumentation, medical equipment and other a permanent magnetic field devices and equipment. It is usually need surface treatment according to customer's requirements to protect magnet. Different coating Metallic Zinc, Nickel, Nickel+Nickel, Copper+Nickel, Nickel+Copper+Nickel, Gold, Organic Epoxy, Nickel+Epoxy coating . Permanent magnet, NdFeB magnet is an alloy magnet made from Nd,Fe,B and other metal elements,which has the high remanence,high coercive force,high energy and high performance/cost ratio.The highest magnetic properties is from 33MGOe to 52MGOe,and we are able to control the magnetic properties within the range as you demanded,like SH,UH,EH such high stable properties could be produced as per your industrial application.
