Neodymium Block Magnet - 20mm x 12.5mm x 3.3mm | Phosphorus Coating

Magnetic Product Description:

This rare earth block magnet has a length of 20mm x 12.5mm x a height of 3.3mm and has a magnetic flux reading of 2302 Gauss and has a pull force of 3.9kilos against 3 mm mild steel. It is identified by the amf magnetics part number 22022A. It has a phosphorous coating.


Uses for our rare earth block magnets:

This Neodymium block magnet is a handy size for a multitude of applications and it is particularly sought after by those in the building industry. There is a Phosphorous coating on this block magnet for purpose of passivation, to assist in the prevention of chemical reactivity. This coating helps to prevent corrosion due to exposure to high humidity environments making it well suited to applications that are outdoors or exposed to the weather.

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.
