Various types of permanent magnet products
(1) product shape and specifications
As the different types of permanent magnets of different materials, their hardness and plasticity vary greatly, which also makes their processing performance, processing accuracy are also different. Usually depending on the practical application, plus the permanent magnet products into different shapes, as shown in the following table for the common description of several magnet shapes. In addition to these common shapes, but also according to the actual application of the magnet into other irregular shapes, collectively known as shaped magnets.
|Representative letters||Shape||Shape symbol||Symbol Description||Display method of specification|
d: inner diameter
|Block magnet with hole||S||L:length|
|Arc & Wedge Magnets||A|
r: inner radius
R: Radius of the outer circle
d: arc height
c: thickness (back height)
Several types of permanent magnets, neodymium rare earth magnet, SmCo（samarium cobalt magnet）, ceramic ferrite and Alnico these types of magnets, due to the greater hardness, mostly out of regular rules of the block. The bonded NdFeB and rubber magnetic, due to the presence of organic matter to make it better mechanical properties, can produce a variety of complex shape of the magnet, and high dimensional accuracy. In particular, flexible magnetic material, which has the characteristics of good flexibility, flexibility and twistability, it can be processed into a strip, roll, sheet, block, ring and various complex shapes, you can also Its made of various colors of the product. The following figure shows the pictures of various types of permanent magnets.
