Neodymium Disc Magnet - 4.75mm x 1.5mm | Gold Coating

Magnetic Product Description:

This Rare Earth disc has a diameter of 4.75mm and a height of 1.5mm. It has a magnetic flux reading of 3364 Gauss and a pull force of 290 grams. This magnet is identified by AMF Product Code 20080A.

Uses for our Rare Earth Disc Magnets:

This Gold Coated Neodymium Magnet is an appealing choice for creative applications and popular with Jewellery Makers, Artists and Craftspeople who prefer the appearance of the gold coating. The gold plating also provides functional benefits due to the unique properties of gold including corrosion-resistance and thermal and electrical conduction, making it suitable for specialised applications.

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.
