High Grade N35-N52 Multi-Polar Sintered Neodymium Magnet With High
Magnetic Flux Density
Product Description:
Sintered Neodymium Magnets are a kind of permanent magnets made of
Neodymium-Iron-Boron (NdFeB) magnetic alloy compound. Due to their
extremely high magnetic flux density and outstanding stability,
they are widely used in various industrial applications. The
sintered neo magnet can be customized to meet customer's specific
requirements in terms of size, pull force, and magnetic
performance. High quality neodymium material used in the
manufacturing process ensures the magnets have superior magnetic
flux density and high pull force. With stable magnetic performance,
sintered neo magnets are long-lasting and reliable.

Manufacturing process for magnets (outline):
| Mixing | 1.Mix the ingredients. |
| Melting | 2.Dissolve the mixture at high temperature and prepare an alloy. |
| Fine pulverization | 3.Turn the alloy into fine powder. |
| 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. |
