Magnetic Product Description:
This Self-Adhesive Neodymium Disc Magnet has a diameter of 20mm and a thickness of 4mm. It has a grade of N42 and pull force of 6.16 kilograms. This product is identified by AMF Magnetics Product Code 20016B.
This type of Self-Adhesive Neodymium Disc Magnet has 3M™ VHB™ (F9473PC) Adhesive on the NORTH side, providing excellent long-term holding power. This type of adhesive is superior for bonding metal trim, and bonding flexible circuits to aluminium rigidities or heat sinks. The adhesive is transparent and ideal for use in many interior and exterior applications. These magnets are commonly used in Industrial Joining and Metal Fabrication.
- 3M ™ VHB ™ (F9473PC) Adhesive is 0.25 mm 100MP high-performance acrylic with 107 microns 26 kg poly-coated kraft paper liner - printed.
Uses for our Rare Earth Disc Magnets:
Neodymium Discs are easily fitted into other products with very little consequence to the operation of these products. In fact, they are often used to improve the performance or appearance of many modern products or artistic works. They are sometimes retrofitted or otherwise incorporated into the early product design stage where they are used to create magnetic joins between component parts or even act as switches that operate electrical systems. This small and powerful Neodymium disc has been designed with a highly practical 3M adhesive backing so it can be applied to various materials, surfaces and circumstances. The magnet can attach to non-ferrous items so they become compatible with metal surfaces in the kitchen, shed or office.
Home and commercial maintenance problems can often be solved with the application of a strong yet unobtrusive Neodymium Disc magnet. Tradespeople and maintenance workers find countless ways to use these strong Neodymium disc magnets during their workday. Scale model makers are constantly finding new ways to apply magnetic bond to help their projects appear more lifelike or to operate more practically. Magnetic power is permanent under most conditions which makes these disc magnets a highly cost-effective alternative to the more traditional fastening systems.

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.
