Neodymium Disc Magnet - 39mm x 18mm | N45H | High Temperature

Magnetic Disc 39mm x 18mm Product Description:

This neodymium magnetic disc has a diameter of 39mm and a height of 18mm. It has a magnetic flux reading of 4646Gauss and a pull force of 45.85 kilos. It is identified by the AMF magnet part number 20001E.


Uses for our Neodymium Rare Earth Disc Magnets:

Neodymium Disc magnets have flat, round pole areas that make them ideal for holding purposes. This extremely strong disc magnet with a thickness of 18mm projects a magnetic field that is able to penetrate materials like cloth, cardboard, vinyl, or acrylics. It can then bond with either metal or another correctly aligned magnet placed on the other side of that material. Printing companies and many other producers of retail merchandise find the strength and non-invasive nature of Neodymium magnets to make them a convenient tool for the creation of advertising and signage products. Magnets in strategic locations can secure unrolled sheeting in a flat position while cutting or printing takes place and without creasing or piercing the finished product.

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.
