Neodymium Disc Magnet 4mm x 2.4mm N50 | Gold Coated

Rated 5.0 out of 5
Based on 1 review
Product Code D-D4H2.4-N50AU
Pull Force* 0.489 kg
Gauss 5569
Grade N50
Coating Gold (Au)
Direction of Magnetisation Through Height
Dimensions Height:2.4mm, Outside Diameter:4mm
*Measured against up to 10mm mild steel.

This gold-coated Neodymium disc magnet has a pull force of 0.489 kg, Gauss 5569, Grade N50. It has a height of 2.4mm and a diameter of 4mm and it is magnetized through height. 

 When it comes to elegance in design, nothing beats gold, and these tiny gold-coated disc magnets are perfect for any application where looks matter. Delicate and strong, our gold-coated Neodymium Disc are among our tiniest, but don’t let their size fool you - they pack a might punch. They are perfect for any application where a more refined appearance is required. They are often used in applications in museums, art galleries and exhibition spaces where aesthetics are an important part of the overall purpose of the magnet.

Craftspeople and hobbyists also find this disc the go to magnet as a clasp and to hold model making materials in place.  It’s not all about looks however - the gold plating also has important functional purposes, including corrosion-resistance and thermal and electrical conduction making them ideal for many specialised applications in electrical devices in security equipment, warning systems and monitoring devices and also in a wide range of electronic 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.

Stay and enjoy.

Look your products are all good. Excellent even. So why need reviews. Is your self esteem not up to it.

BTW I can't navigate your search engines happily. I want a small magnet, circular with a hole I can use to attach to the magnet guide rail. Whee is it?
