Alnico Button Magnets with Fixing Hole | Ø12.7mm–31.8mm | Up to 4.8kg Pull Force

Eclipse Magnetics Alnico Button Magnets are compact cylindrical permanent magnets designed for applications requiring precise positioning, secure mounting and excellent magnetic stability at elevated temperatures.

Each magnet features a central fixing hole and machined slot to support secure installation into jigs, instruments, relay devices and other engineered assemblies. Manufactured from high-quality Alnico alloy, they provide stable and consistent magnetic performance in demanding industrial, electrical and laboratory environments.

The range is available in five sizes, from 12.7mm to 31.8mm diameter, with pull forces from 0.7kg up to 4.8kg. This provides a choice of compact and higher-strength options depending on the mounting space and holding requirements of the application.

With operating capability up to 550°C, these Alnico button magnets are particularly well suited to temperature-critical applications where long-term magnetic stability and reliable performance are required.
