Epoxy Coated High-Performance Traction Motors
Product Description:
Sintered Neodymium Magnet, also known as Neo Magnet, is a type of
Powder Metallurgy Magnet made of neodymium, iron, and boron as main
ingredients. This type of magnet is renowned for its strong and
powerful magnetic properties. In comparison to other magnet
materials, Neodymium magnet is a cost-effective solution for
producing powerful magnets. It is highly temperature resistant and
corrosion resistant, making it suitable for a wide range of
applications.
Sintered Neodymium magnet is available in various shapes and sizes,
and with various coating options, such as Nickel, Zinc, and Epoxy.
The magnetic orientation can be Axial, Multi-polar, or customized
to suit customer needs. The temperature resistance of these magnets
is high, and they offer excellent corrosion resistance. Sintered
Neodymium Magnet is also reasonably priced, making it an attractive
option for businesses.

| Molding in a magnetic field | 4.When pressing the fine powder, apply a magnetic field to it and
prepare
a molded product of powder with aligned directions of
magnetization. |
| Sintering and heat treatment | 5.Sinter the product at about 1,100℃, and then subject it to heat
treatment at
about 600℃ to increase its magnetic characteristics. |
| Processing | 6.Process the manufactured magnet base material and finish it into
the product shape. |
| Surface treatment | 7.Subject the product to surface treatment in order to make it
rustproof. |
| Magnetization | 8.Apply a magnetic field to give the magnet magnetism. |
