High-quality rare earth neodymium materials makes the magnetic energy of neodymium iron boron magnets ten times stronger than that of ordinary magnets.
Sintered Neodymium magnets are prepared by melting raw materials in a vacuum or inert gas atmosphere induction furnace, processing them in a strip caster and cooling to form alloy strips. The strips are crushed and ground into fine powder with particle size of microns. The powder is then compacted in an aligning field and sintered into dense blanks. Finally, the blanks are machined into specific shapes, surface treated and magnetized.
1.Shape of neodymium magnets
We provide a wide customizable range of shapes and sizes, including round, rectangle, ring, bar, and custom designs to meet diverse industrial, electronic, household, and DIY application needs.
2.High-Precision Manufacturing
With precision grinding and cutting, tolerances of ±0.05mm can be achieved during the manufacturing process.
We support more extreme tolerances.
3.Plating / Coating of neodymium magnets
Neodymium iron boron magnets require surface coatings to prevent corrosion. There are a variety of options for coatings,but nickel is the most common and usually preferred Our nickel plated magnets are actually triple plated with layers of Ni-Cu-Ni. Other options such as zinc, chromium, gold, epoxy resin, plastic, teflon, etc. Each coating offers a unique appearance, performance, and typical applications.

4.Magnetization direction of neodymium magnets
Magnetization is the process of applying a magnetic field to a permanent magnetic material along the direction of themagnetic field orientation and gradually increasing the magnetic field intensity to reach a technical saturation stateIn addition to the two relatively simple magnetization directions of axial and radial, sintered neodymium iron boron ringscan also undergo muti-pole magnetization as per actual needs, that is, after magnetization, they can present multiple N-poles and S-poles on a single plane. The multi-pole ring requires the use of specially designed magnetization fixtures, thusincurring additional costs for the magnetization fixtures.
We have over hundred types of magnetizing fixtures that can meet your special customization requirements.

5.Compliance, safety, and high quality
We hold multiple patents and operate under an ISO 9001-certified quality management system.
Our neodymium magnets have obtained CE, SDS, RoHS and REACH certifications—eco-friendly, non-toxic and free of regulated harmful chemicals. Boasting strong magnetism, stable performance and precise dimensions.
