Neodymium Discs

Rare Earth disc magnets are a key component in all manner of tools, equipment, audio products and an endless array of household items. A disc magnet is defined as a round magnet with a larger diameter measurement than height measurement. These round magnets are so commonplace you have almost certainly used one today. Starting at just 2mm in diameter, we stock tiny Neodymium disc magnets right through to large industrial scale magnets.

You won’t find our range of stock or quality of magnets at any general hardware store like Bunnings. Our website allows you to buy disc magnets and any other magnetic products from the comfort of your home and we deliver Australia wide.


Choosing the right magnet

We know from our customers that it can be challenging to select the best magnet for their purposes. The shape of the magnet is just one consideration when making your selection. A disc magnet has a wide surface meaning it provides a stable magnetic hold which is not easily displaced. The low profile of a disc magnet means minimal bulk is added when the thin magnet is attached externally to an object. Similarly it’s shallow profile allows for it to be inset within an object for a flush exterior. The circular shape is ideal for anyone working with tools as a drill hole can be utilised to create the perfect housing.

The strength of the magnet is another core aspect customers need to consider. Generally, a magnet's strength is determined by the amount of Neodymium magnetic material present. However, the grade of the magnet is also a factor. An N52 grade magnet is the most powerful grade of Neodymium and a magnet of this grade would outperform a magnet in the same dimension of a lower grade. There are also grades that provide greater resistance to high operating temperatures than a normal Rare Earth magnet.

The industry standard is for Neodymium magnets to be Nickel coated (Ni), this gives Rare Earth magnets the shiny silver appearance they are known for. However, there are a number of alternate coatings available. Coating such as Gold (Au) and Parylene C provides superior performance in damp environments as they have greater resistance to corrosion due to the effects of moisture.

Rubber and plastic are popular choices of coatings for customers that wish to use their magnets in situations that cause an impact on the magnet; such as gates opening and closing with force. Neodymium is a brittle material and it can easily splinter or fracture.

Our range is diverse and we keep ample stock available in our Sydney warehouse. We understand that some applications need a custom product, please don’t hesitate to contact us if you would like a quote for a batch of custom made magnets.

We have a knowledgeable team and are happy to help our customers find the best magnets for their needs. Please contact us if you have any questions or would like to discuss bulk order discounts.

The Pull Force listed for each magnet is based on lifting 10mm thick steel vertically. Magnets on a vertical surface (of 10mm thick steel)  are generally able to hold around 30% of the pull force listed due to the effects of gravity and the lack of traction between the surface and the shiny magnet.
