Compact magnet systems with a steel shell with h6 fit tolerance. These pot magnets are suitable for gluing, pressing and shrinking. Thanks to the shell of these pot magnets, the magnetic field strength increases and they are more resistant to corrosion or chemicals. Pot magnets have a single attraction surface; this prevents the spread of the magnetic field.Pot magnets with h6 fit tolerance are available in various sizes and types such as neodymium, samarium cobalt and AlNiCo.

Construction of NdFeb pot magnets

What does a neodymium pot magnet consist of?

These super-strong pot magnets are made of the alloy neodymium-iron-boron (NdFeB), which Goudsmit markets under the brand name Neoflux®. The shell - or pot - provides magnetic shielding. Goudsmit supplies neodymium pot magnets with a brass or steel shell. The holding surface has a protective coating to prevent corrosion.
 

Operating temperature

What temperature does magnet strength loss occur at?

Neodymium cylindrical and flat pot magnets have an operating temperature of up to 80 °C. When heated to this temperature, the magnet loses 15 to 20% of its magnetic strength. This is not permanent; the force is restored when the magnet returns to the normal ambient temperature.
External magnetic fields may also cause loss of magnetic force. An air gap or non-magnetic materials located between the magnet and workpiece reduce the tensile force.

Important to know

Loss of holding force

To prevent loss of holding force due to magnetic short-circuit, neodymium magnets with a brass shell may not be pressed directly into iron. Always maintain a certain distance between the brass shell of the pot magnet and the iron. Contact Goudsmit for specific recommendations.
 
Tooling the magnet without loss of tensile force:
The magnet strength remains the same when the magnet system is shortened down to a maximum value of A. See the specified value for the relevant item.
