NdFeB magnet
Neodymium magnets are the strongest permanent.
RareEarth 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.
Block magnet
Neodymium block magnet, also known as rectangular magnet, square magnet or bar magnet, compared with disc magnet, block magnet is not as commonly used as disc magnet, but their straight line and clean edge offer a pleasing and different visual appearance, what's more, it provides a bigger surface area than disc magnet of same diameter.

Grades of Neodymium Magnet
The temperature ratings are standard (no designation) - M - H - SH - UH - EH. You find the temperature rating of each grade on our specifications of neodymium magnets page.
| N series: N35 N38 N40 N42 N45 N48 N50 N52- 80°C |
| M series: 35M 38M 40M 42M 45M 48M 50M-100°C |
| H series: 30H 33H 35H 38H 40H 42H 44H 46H 48H-120°C |
| SH series: 30SH 33SH 35SH 38SH 40SH 42SH-150°C |
| UH series: 28UH 30UH 33UH 35UH 38UH 40UH-180°C |
| EH series: 28EH 30EH 33EH 35EH-200°C |
| AH series: N28AH N30AH N33AH N35AH-220°C |
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 magnets much 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.

Applications
Block magnet is widely favoured for clamping applications, magnetic sweeper applications, magnetic separators in the food industry, winde tube generators, flow control systems & water conditioning application and other related industrial applications.
