Enhance your projects with the exceptional performance and reliability of premium neodymium disc magnets.

18mm x 4mm Neodymium Disc Magnets
These neodymium disc magnets are a practical solution for both DIY tasks and industrial applications. At home, they can be used to create magnetic organisers, secure items, or build custom fixtures. In industrial environments, they play a key role in manufacturing and engineering, where they are used for holding components in place during assembly or ensuring precision in positioning. Their strength and versatility make them an essential tool for a wide range of tasks. To learn more about available magnet shapes, click here.

Magnet Grade: N52
These N52 neodymium magnets deliver some of the highest magnetic strength available, featuring a maximum energy product of approximately 52 MGOe (Mega Gauss Oersted). Designed for applications that require powerful and consistent magnetic force, these magnets are engineered to perform reliably in even the most challenging conditions. Their extraordinary strength makes them a top choice for projects demanding maximum magnetism. To learn more about magnet grades, click here.

Other types of disc magnets
As an alternative to neodymium disc magnets, you can also find ferrite disc magnets in our online shop. They do have a lower adhesive force compared to to the round magnets made of neodymium, but they are also less expensive. In addition, ferrite magnets are ideal for outdoor use and can withstand higher temperatures. Disc shaped Copper Coating NdFeB Magnets 12x6mm N42

Neodymium magnets: Especially strong as discs
We offer our disc magnets in more than 100 different sizes. They have adhesive forces ranging from 25 g to 140 kg, so you can find the right product for your needs. They are so-called raw magnets where the magnetic flux lines are dispersed in the air around the magnet (in contrast to pot magnets). This large areal distribution allows for attraction of metallic objects from a large distance.

Direction of magnetisation of disc magnets
Most of our neodymium disc magnets are axially magnetised. This means the poles are located above and below on the circular surfaces. A few round magnets are diametrically magnetised (poles left and right), which we have marked for you. Disc Round Copper Plated Magnets 10mm x 10mm N45

Possible application areas:
Furniture construction: lid and drawer clips with especially flat self-adhesive or screw-on magnetic discs
Metal, booth and store construction
Workshop
Loudspeaker construction
Model making
Purse and clothing clasps to sew-on

Our strong round magnets can be easily glued into depressions (e.g. for knife racks) or on the backside of small items, for instance to create magnetic board or fridge magnets.
Tip: Use our tool to calculate the adhesive force of disc magnets at various distances. Disc Copper Plated Neodymium Magnet 8mm x 8mm N45
