Permanent Sintered Rare Earth Magnet Block Neodymium N35 N42 N45 N52 Widely Industrial Applications

Product Description:

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.

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.

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.
