Neodymium Disc Magnet - 7mm x 3mm

Neodymium Rare Earth Magnetic Disc Product Description:

AMF is Australia's number one supplier of powerful neodymium magnetic products. AMF uses the highest quality Rare Earth magnetic material. This Rare Earth Disc Magnet has a diameter of 7mm and a height of 3mm. Although a smaller magnet, this product is extremely strong considering. It has a magnetic flux reading of 4100 Gauss and a pull force of 1.04kg.


Uses for our Super Strong Neodymium Disc Magnets:

This product’s strong magnetic force for compact size is what makes it extremely popular in many industries. This permanent magnetic disc finds widespread application in businesses reliant on visual communication to attract potential customers. These small magnets are reliable, reusable and easily removable. As such, many companies use these disc magnets to construct custom displays.
These powerful rare earth magnets are used in many industries. These include retail joinery companies, the automotive industry and light and heavy industrial workshops. Their compact size allows designers and tradespeople to easily make adjustments. Discs are commonly used as fixing or fastening method to allow for simple repositioning with little or no damage. This differs from the often permanent damage of screws or bolts.

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.
