Product Description

Big Size Neodymium Disc Magnet Magnetic Materials Disc NdFeB Magnet

Premium NdFeB grades range from N30 to N52, which is the highest grade available in today's market. From micro-sized disc magnets measuring 0.1" in diameter to large cylinder magnets that hold up to 68 lbs, we have a vast selection of neo-disc magnets to choose from for virtually any application.

The Ultimate Magnets! Neodymium Iron Boron (NdFeB) is used to manufacture the most powerful magnets per unit volume that are commercially available today.

It is used where a small size and maximum power are needed. Neodymium Magnets exert very high forces and can attract each other through unbelievably large distances making them very popular for a wide range of applications including scientific experiments, packaging, security, lighting, display, and magic acts to name a few. They also have an immense and unbeatable resistance to being demagnetized, making them ideal for repulsion applications as well as attractive applications.

Magnetization Direction

The common direction of magnetization is shown in the picture below:

1> Disc, cylinder, and Ring shape magnets can be magnetized Axially or Diametrically.
2> Rectangle magnets can be magnetized through Thickness, Length, or Width.
3> Arc shape magnets can be magnetized Diametrically, through Width or Thickness. The special direction of magnetization can be customized as required.

Grade&Coating

Support all magnet plating, like Ni-Cu-Ni, Zn, Epoxy, Gold, Silver, etc.

 

1>Neodymium magnets are made of Neodymium, Iron and Boron. If left 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.

2>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 magnets much more durable than the more common single nickel-plated magnets.
3>Other options for coating are zinc, tin, copper, epoxy, silver, and gold.
