Magnetic Product Description:
This rare earth block magnet has a length of 20mm, a width of 11.5mm and a thickness of 3.3mm. It has a magnetic flux reading of 2419 Gauss and a pull force of 3.7 kg against 3mm mild steel. It is identified by the AMF magnetic part number 22022C and has a phosphorous coating.
Uses for our rare earth block magnets:
Phosphorus coatings create an inert protective barrier for the surface of the magnet making this Neodymium Block a good choice for outdoor applications and where exposure to the weather is unavoidable. Unlike thick Epoxy coatings that interrupt direct contact of the magnet to a metal surface, Phospherous coatings are powder-like and do not affect the strength or holding power of the magnet. Magnets like these are used in sensors to activate alarms and locks in the Security, and Surveillance industries.
No FAQ available
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.
