Hi Rochelle,

What a wonderful review to receive! We're absolutely thrilled to hear these tiny 4mm x 2mm neodymium disc magnets turned out to be perfect for your needs.

We completely understand your initial concern about the size - at just 4mm diameter and 2mm thick, they really are quite compact! But these little powerhouses pack impressive N42 grade magnetic strength into that tiny disc profile, making them ideal for applications where you need reliable holding power in a very small form factor.

They are very strong magnets although, quite expensive for 25 of them ($9.25). I’d say that you should only buy these in massive bulk. I did have trouble when using these next to each other (I had to hammer some of them into a slot) so just be aware of this. Overall, I would buy these again.

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.
