Neodymium Disc Magnet - 20mm x 10mm

Magnetic Product Description:

This rare earth disc has a diameter of 20mm and a height of 10mm. It has a magnetic flux reading of 4455 Gauss and a pull force of 11kg. It is identified by the AMF magnet part number 20012.


Uses for our rare earth disc magnets:

When the going gets tough, the tough get going. For neodymium disc 20mmx10mm magnets allied to tools and equipment in the mining industry to blast, drill, cut, crush, load and process rock, that is saying something. The phrase ‘rock hardness’ is commonly used in the industry and helps explain why tools and equipment associated with mining are of a different grade and scale compared to other tools and equipment made for other industries.

The task of excavating, transporting and processing of ore (rocks) requires a dedicated team of workers and purpose built tools and machines of a scale and cost the world has never seen before. It is hard to imagine what else, apart from mining, these rock breaking pieces of equipment could be used for.

For such punishing work, steel fabricated technologies are a necessity in the mining industry. These 20mmx10mm neodymium disc magnets, embedded in the mining tools and equipment, can be found all over the mine site. From helping out the rotary blast hole drill bits readying another section of rock for dynamiting, to the dozer mounted long wall boring attachment and the three storey driverless dump trucks, magnets mix with the toughest of machines, for the heaviest work, in the most demanding of all conditions. Like they say. When the going gets tough, the tough get going.

Attaching something to something else is common in the extreme. Also referred to as fastening, the Concise Oxford dictionary allows ‘fasten’ to mean, ‘secure by some tie or bond’. In the fastening family, these neodymium-disc 20mm-10mm magnets feel right at home. Still operating at temperatures of up to 200 deg.C these magnets are known to generate excellent cost to performance ratios.

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.
