N52 strong Neodymium Block Magnet
Neodymium block magnet
Neodymium block magnet is called as block Neodymium magnet, NdFeB
block magnet, or Neodymium rectangular magnet. It is a rectangle
shape, and is the most common shape of Neodymium magnet.
Most sizes of Neodymium block magnets are machined from a large
magnet block. How is the large Neodymium magnet block produced? In
fact, the production process for rare earth Neodymium magnet
belongs to powder metallurgy. In this process, a suitable
composition of raw materials are pulverized into fine powder,
pressed and heated to cause densification via liquid phase
sintering, which is the reason that it is often called sintered
rare earth magnet. Through melting, jet milling, sintering and
aging, a large magnet block or semi-finished Neodymium magnet block
is produced with a rough surface and only approximate dimensions.
In order to get the final Neodymium block magnet with smaller and
more accurate size, the large magnet block will enter into the
machining process, if the magnetic properties are tested OK to meet
the requirement. During the machining process, more attention
should be paid to size, tolerance, and especially the orientation
direction so as to ensure Neodymium block magnet quality.
If the size of the final Neodymium block magnet is big, for
example, 100 x 60 x 50 mm, the semi-finished magnet size will be
produced similar to the final size, because it’s not easy or
economical to produce a semi-finished magnet which can be machined
to several or even two final block magnets. The simple grinding
process may machine one semi-finished magnet to one final Neodymium
block magnet!
Neodymium block magnet has three directions, like length, width and
thickness, and generally the Neodymium magnet size is described as
L x W x T, such as 30 x 10 x 5 mm. Generally speaking, the shortest
one of the three dimensions is the orientation direction. However
in many cases the customers might have specific requirement about
the orientation, for example for the longest dimension, or multi
poles on the same surface…
