**Magnet size is prior to rubber coating

The neodymium magnets in this group are entirely coated by a layer of rubber, which provides the following advantages:
Scratch protection: Delicate surfaces, such as whiteboards or magnetic glass boards, are well protected
Waterproof: These magnets are rustproof and can be used outdoors as long as the rubber coating stays intact
Friction: The rubber coat substantially increases the magnetic adhesive force in shear direction
Due to the rubber coating the maximum adhesive force of these magnets is slightly lower, however, compared to similar-sized neodymium magnets without coating.

What Kind of Coatings Available for Magnet?
Due to iron element in the sintered neodymium magnets, coating is a very important part of neodymium magnet. Although we can provide a variety of options for plating, nickel is still the most common and usually preferred.
Our nickel coated magnets are actually triple plated with layers of nickel, copper, and nickel again. This triple plating keeps our sintered neodymium magnets much more durable than the magnets with single nickel plated. Some other options for coating are zinc, tin, and plastic, epoxy, silver and gold. You can find more information from our Plating of Sintered Neodymium Magnet Page. Ø 16.8 x 4.4 mm Black Rubber Coated Neodymium Disc Magnet

How Many Types of Magnet Shapes can We Make?
Our sintered neodymium iron boron magnets are customized in a variety of shapes including:
Common shapes: disc, ring, cylinder, block, bar
Irregular shapes: segment, countersunk, T shape, bread shape, triangle, oval, half disc
Other custom shapes which can be realized by CNC precision machining
