Hi there,

That's fantastic to hear! We're delighted these 20mm x 2mm neodymium disc magnets are working so well for your hat hangers and that they're proving popular with the public. What a clever application - the slim 2mm profile combined with the strong N42 neodymium magnetism really does make these perfect for vehicle accessories where you need reliable holding power without bulk.

Thank you for the fantastic 5-star review and for choosing AMF Magnetics!

Excellent product

Very well packed and good safety information card included. I'm going to use these inside a guitar to attach an external support so I can swap the support between guitars (hope that makes sense).

I'm copying the internal magnet setup as it's currently too expensive to get the actual part from the USA, so I'm going to make my own.

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.
