Neodymium Block Magnet - 4mm x 6mm x 12mm | N48M | Epoxy Coated | High Temperature

Magnetic Product Description:

This rare earth block magnet has a length of 12mm, a width of 4mm and a height of 6mm. It is magnetised through the 6mm height. The magnet has a black epoxy coating and a N48M grading with operating temperature up to 100°C.  It is identified by the AMF magnet part number B-W4H6L12-N48M.


Uses for our rare earth block magnets:

Our Neodymium Block magnets come in a huge range of dimensions and strengths. Neodymium, or Rare Earth as it is otherwise known, is the strongest type of permanent magnet having replaced more traditional types of magnets in most commercial operations. Often described as silver magnets, Neodymium magnets have a chrome-like Nickel-plated surface that is distinctively different from other types of magnetic material. AMF staff are often contacted by craftspeople and people looking for DIY home improvement solutions and these powerful magnets are often the ideal solution. The term block magnet also includes magnets that are sometimes referred to as bar magnets, rectangular magnets or square magnets.

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.
