yes
They are very good. But it does not have a pull force of 5.08KG and they chip very easily. Not the best magnets but still very good.

Rated 5.0 out of 5
Product Code
20025
Pull Force*
5.08 kg
Weight
8 gm
Style
Rare Earth Disc magnet
Coating
Nickel (NiCuNi)
Direction of Magnetisation
Axially magnetised
Dimensions
Height:10mm, Diameter:12mm
Magnetic Product Description:
This rare earth disc has a diameter of 12mm and a height of 10mm. It has a magnetic flux reading of 5402 Gauss and a pull force of 5.08kg. It is identified by the AMF magnet part number 20025.
Uses for our rare earth disc magnets:
This Axially magnetised disc has the poles located on the top and bottom circular face. It is suitable for embedding into timber or plastic with epoxy glue where Imperial half-inch diameter is required. The height dimension of 10mm is almost matching the pole diameter and this considerably increases the magnetic energy it produces and therefore, its holding ability. Commonly used for metal separation and decontamination, water conditioning, electric DC motors, magnetic stirrers, metal detectors, tool or knife holders, holding clamps, wall stud and noggin finders, magnetic healing therapy and box top or lid closures.

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.
