They are obtained by sintering Of Rare Earths.
This new version has a black epoxy coating, suitable for interior design.
This kind of magnets reaches the highest values of magnetic attraction; for this reason, they are recommended where great power is required in small spaces. Another advantage is the maintenance of the magnetic charge which is higher than in other types.
It's recommended to respect the max operating temperatures indicated in Physical Magnet Data Sheet.

All measurements are in millimeters. Other sizes and shapes on request.
The magnetization is axial. Other kind of magnetization on request.
