Neodymium Block Magnet - 20mm x 20mm x 12mm | Epoxy Coating | N42H with Mid Groove | High Temp 120 deg
Product code: 22016
Neodymium Block Magnet - 20mm x 20mm x 12mm | Epoxy Coating | N42H with Mid Groove | High Temp 120 deg
Product Description:
This magnet measures 20 mm L x 20 mm W x 12 mm H. It has an 12 mm groove which is 1 mm deep, and is coated with Epoxy. It has a magnetic flux of 4606 Gauss and a pull force of 16.5 kg.
Uses for our Rare Earth block magnets:
These magnetic blocks are often used by specialist design firms. Magnets are starting to outperform traditional fasteners like bolts, screws, rivets, nails and glues. Especially when it comes to plastics. Plastics are increasingly popular with industries all over the world. Magnets can be placed into pockets of plastic fabrications (tools, toys, televisions) to secure and fasten plastic parts without damage to the surface.
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.
