Uses for our Rare Earth Block Magnets:

Although compact in size, these Neodymium Block Magnets are strong and their precise dimensions make them ideal for Mechanical Engineers, Industrial Designers, and Fabricators. The blocks are ideal for testing design concepts and can be used as a singular magnet or in a series which allows the holding strength to be adjusted throughout the prototyping phase of product design. Two or more of these magnets embedded in plastic, timber or resin can create a concealed join for component pieces. This offers instant assembly or dismantling, two properties that are advantageous in any product that comprises multiple components; handy for cleaning, packing and transportation purposes.

We supply this magnet to pool companies, printers, health service providers, web customers, microprocessor engineers, car, boat, jetski cover accessory manufacturers and more. Neodymium magnets are used for industrial measuring, weighing, automating, fastening, experimenting, designing and printing.

Closure for letterbox lid

My stainless steel (non-magnetic) letterbox lid regularly blew open on windy days, so the mail got soaked. Two little neodymium block magnets epoxy glued to the lid, mating with galvanised hex head set screws on the base solved the problem beautifully. These little block magnets are great for closures.

NB: Ranges are indicative for product category, please check individual products for specic values within that range.

The most common coating for Neodymium magnets is Nickel + Copper + Nickel (Ni + Cu + Ni). This coating offers the magnet relatively good protection from corrosion and passive applications. If the magnet will be exposed to moisture or liquid then consider the use of an organic coating such as Epoxy. A hard wearing coating, Epoxy is suited to applications where the magnet will come under some friction or knocking.

Magnets are readily available in Blocks, Discs, Cylinders & Rings. AMF Magnetics specializes in the supply of short-run prototype magnets including Arc Segments, various magnetic orientations etc. If you need a magnet size that we don't carry in stock, submit a Design-a-Magnet enquiry for a quote on your custom magnet design.

Neodymium magnets are offered in several different grades. The first section N30-54 has an operating temperature of up to 80 degrees. Most of our stock only goes up to N38. The second section, denoted with the "M" prefix after the grade has an operating temperature 100 degrees. After this the grades are "H", "SH", "UH" & "EH". In order for the magnet to withstand a higher operating temperature, during production more of the raw material PrNd is incorporated as these elements have a naturally occurring resistance to high temperatures.
