There are some other elements that may be used for purposes of improving the coercivity, gaining lower weight loss and other special characteristics. The sintered Neodymium Iron Boron magnet has higher magnetic properties compare to Samarium Cobalt magnets, however it is more easily oxidized and generally does not have the same temperature resistance. The highest energy products for NdFeB could reach 50 MGOe commercially or more. These materials are only used in very selective applications due to the cost. Cost is also driven by existing intellectual property rights of the developer of this type of magnets. Their high energy products lend themselves to compact designs that result in innovative applications and lower manufacturing costs. NdFeB magnets are highly corrosive, so that various surface treatments include nickel, Zinc and gold plating as well as epoxy resin coating. Magnet block is the most permanent magnet in the contemporary. Due to it have good remanence, coercivity and high performance, sintered NdFeB magnet have best magnetic, can support about 640 times of its weight. Now it have been widely used in electronics, electrical, mechanical, medical equipment and others. 1)Material:sintered NdFeB magnet 2)Garde:N35-N38-N40-N42-N45-N48-N50-N52 3)Nickel,Zn etc coating Sintered NdFeB neodymium magnet block 1)Garde:N35-N52,N35M-N48M,N35H-N45H,N33SH-N42SH,N30UH-N40UH,N30EH-N35EH. 2)axially,diametrically,multi-pole magnet disc. 3)Ni,NiCuNi,Zn,Black Expoxy,Black Nickel,Ag,AU,etc coating. 4)Application:Acoustics,Motors,Windmill,Transportation,IT industryequipments,Home appliance,Loudspeaker,,Communication etc. 5)shipment way:By Sea/air/express are available.
