Magnet Disc

Neodymium (NdFeB)

Neodymium Iron Boron (NdFeB) magnet has high remanence, high coercive force, high energy product, and high performance/cost ratio.

It is easily formed into various sizes, widely used in motors, sensors, meters, sound devices, magnetic separators, automobiles, aviation, aerospace, and other applications. It is prone to corrosion in humid environments, so it usually needs surface treatment according to customers' requirements. The coatings we can offer include: nickel, zinc, gold, silver, epoxy, and parylene.

1. The coatings of magnets are in paint, zinc, black zinc, nickel, nickel, copper, nickel, chromium, etc. are mainly anticorrosive

2. Neodymium iron to boron material is characterized by hard and brittle, magnetizing weight is more than 600 times its weight, easy to suck knock. In the operation process, attention should be paid to avoid bumps and disability for small specifications, and more attention should be paid to personal safety and protection for large specifications.

1. Q: Which is the strongest type of magnet? 
    A: Neodymium (more precisely Neodymium-Iron-Boron) magnets are the strongest permanent magnets in the world.

2. Q: What are the size limitations on manufacturing neodymium magnets?
   A: The limits include:
