Overview - Alnico Button Magnets
Ideal for holding, fixing and clamping applications
The Alnico button magnet is a two pole rounded magnet usually with a hole in the centre and a slot separating the two poles. They are generally small in size.
For larger units with greater holding force, the Alnico horseshoe may be a better choice (or a pot magnet). The Alnico button magnets are supplied in natural (uncoated / unpainted) and red paint finishes and are capable of operating at temperatures of up to a maximum of +1022°F (550°C). Other colour options are available as part of our custom made Alnico magnet service - subject to quantities.
