Neodymium Discs

NdFeB Disc Magnets

NdFeB discs are used in a huge variety of applications, from use in Hall Effect Sensors and Reed Switches, through to clamping applications, office use, generator use, educational, etc.

The magnets are supplied in stock sizes varying from 1mm to 40mm in diameter and 0.4mm to 10mm in height. The stock sizes are axially magnetised and supplied with +/-0.1mm tolerances.

We can produce the NdFeB circular disc magnets in different sizes, different grades (strengths and temperature ratings) , different coatings/finishes and in diametric magnetisation as part of our custom magnet (made-to-order) service.
