N52 Neodymium Iron Boron Epoxy Coated Magnet For Sale
Product Description:
Sintered Neodymium Magnets are the world's strongest type of rare
earth magnets. Made from an alloy of neodymium, iron, and boron,
these magnets are extremely powerful for their small size and are
used in many modern applications such as motors, phones, and
headphones. These magnets are available in a variety of grades,
from N35-N52, 35M-50M, 35H-48H, 30SH-45SH, and can be customized to
various shapes, including blocks, arcs, rings, and custom shapes.
The magnets can also be coated with nickel, NiCuNi, zinc, epoxy, or
other coatings to protect them from corrosion, scratches, and other
damage. With a working temperature of 80~220°C, these sintered
neodymium magnets are a reliable and powerful choice for many
applications.

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. |
