    Classification of ND-Fe-b magnets

    Dongyang Aviation Magnetic Ltd | Updated: Apr 13, 2016

    Neodymium-Iron-Boron magnets can be divided into bonded NdFeB and sintered ND-Fe-b in two ways. Bond in fact, injection molding and sintering are vacuum forming by high temperature heat! Neodymium-Iron-Boron magnets, so far has the most powerful magnetic force of permanent magnet. Materials N35-N52; various shapes according to specific requirements and processing: circles, squares, punch, magnetic, magnet, convex, trapezoid, despite these advantages, but surface rust easily, so usually require some protective surface treatment: nickel plating, zinc plating, gold-plated, epoxy-coated, and so on. General application of neodymium-Iron-Boron magnets below the environmental temperature is 80 degrees, but there are also several 200-degree heat. Mainly used in electronics, electric appliances, packaging, electrical, toys, leather, auto mechanics, and so on.
