Rare Earth Neodymium Bar & Block Magnets
- Neodymium bar, block and cube magnets are incredibly powerful for their size, with an approximate pull strength of up to 300 lbs.
- Neodymium magnets are the strongest permanent. Rare-Earth magnets commercially available today with magnetic properties that far exceed other permanent magnet materials.
- Their high magnetic strength, resistance to demagnetization, low cost and versatility make them the ideal choice for applications ranging from industrial and technical use to personal projects.
- Various Shapes：Any size and performance can be customized according to requirements.The highest accuracy can reach 0.01mm
- Magnetic Direction：The magnetization direction of the magnet has been determined during pressing. The magnetization direction of the finished product cannot be changed. Please be sure to confirm the required magnetization direction
- Environmental Protection Coating：We have our own electroplating factory, which supports the customization of various coatings and meets the environmental protection standards

>Neodymium Magnet
Common direction of magnetization showed in picture bellow:
- Disc, cylinder and Ring shape magnet can be magnetized Axially or Diametrically.
- Rectangle shape magnets can be magnetized through Thickness, Length or Width.
- Arc shape magnets can be magnetized Diametrically, through Width or Thickness.
- Demagnetization Curves & Outgoing Inspection Report for Each Neodymium Rare Earth Magnet
- In most cases,it is diametrical magnetized,half of quantity is N pole and the other quantity is S pole.
Platings/Coatings
- Neodymium magnets are a composition of mostly Neodymium, Iron and Boron. If left exposed to the elements, the iron in the magnet will rust. To protect the magnet from corrosion and to strengthen the brittle magnet material, it is usually preferable for the magnet to be coated.
- 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 nickel, copper, and nickel again.
- This triple coating makes our magnetsmuch more durable than the more common single nickel plated magnets. Some other options for coating are zinc, tin, copper, epoxy,silver and gold. Our gold plated magnets are actually quadruple plated with nickel, copper, nickel and a top coating of gold.
Application
1). Electronics – Sensors, hard disk drives, sophisticated switches, electro-mechanical devices etc.;
2). Auto Industry – DC motors (hybrid and electric), small high-performance motors, power steering;
3). Medical – MRI equipment and scanners;
4). Clean Tech Energy – Water flow enhancement, wind turbines;
5). Magnetic Separators – Used for recycling, food and liquids QC, waste removal;
6). Magnetic Bearing – Used for highly sensitive and delicate procedures in various heavy industries.
Manufacturing Process
Sintered Neodymium magnet is prepared by the raw materials being melted under vacuum or inert gas atmosphere in an induction melting furnace and processed in the strip caster and thus cooled to form alloy strip. The strips are crushed and pulverized to form a fine powder ranging from 3 to 7 microns in particle size. The powder is subsequently compacted in an aligning field and sintered into dense bodies. The blanks are then machined to the specific shapes, surface treated and magnetized.
