Square magnets are usually pressed in a tool, sintered (heat treated) and, if necessary, ground to exact tolerances. For special applications it is necessary to machine the magnets on all sides in order to meet dimensions or weight tolerances. These machining stages have to be accomplished with great care because of the high degrees of brittleness and hardness of the material. If it is really necessary to machine all side of a magnet, finishing by sawing or cutting is often more favourable. The surface quality and tolerance of the separated faces correspond to those of ground magnets and further machining is unnecessary. Small magnets with exacting tolerances can be produced by this process alone.
Available Grades of Neodymium Magnets
Many grades of Neodymium exist to support a variety of industrial and commercial applications. The range of Neo grades is typically 33 to 52 MGOe. These ranges allow for balancing cost, magnetic performance, and operational temperature resistance.
HSMAG Magnets has available for sale N35, N40, N42, N45, 50 & neodymium magnets N52 which are the most popular Super Strong Rare Earth Magnets these days. Retail, Wholesale & Bulk neodymium magnets for sale.
Neodymium magnets have poor resistance to corrosion and they can also corrode from the inside out if proper pre-treatment processes are not followed. Oftentimes a multi-layer Nickel-Copper-Nickel plating is applied, but this may not be sufficient for all applications.
Neodymium magnets are very susceptible to elevated operating temperatures and the application requirements should be considered before selecting a particular grade of Neo.
Although most commercial magnets are anistropic, which means they have a preferred direction of magnetization, various pole configurations can be achieved without conflicting with a Neodymium Magnet’s orientation.

Square, ring, disc and segment magnets are the most common types of permanent magnets produced by injection moulding, and they can be produced economically by this method.
In addition to the geometries mentionned, permanent magnets can be produced in different shapes, which should wherever possible be included as part of the moulding. Subsequent modifications to shape are only possible with expensive machining operation and diamond tools. This applies to holes, chamfers, indentations, etc. In this context is should be noted that gores, openings etc, can only be produced in direction of pressing. With anisotropic magnets is not possible to provide these transverse to the preferred direction.
