Overview - Alnico Cylindrical Bar Magnet
Alnico Bar/ Rod Magnets
The alnico rod magnets are also known as alnico cylindrical magnets, alnico cylindrical bar magnets and alnico cylindrical rod magnets. They can be used at temperatures of up to +550 degrees C.
They are termed bar magnets because the distance between the poles is greater than the pole face dimensions (i.e. they are magnetised in the same direction as their longest dimension). The alnico cylindrical bar magnets are supplied as either red painted or natural finish (uncoated, unpainted).
These alnico rod magnets are very popular of sensing applications and for experimental use in schools. The alnico cylindrical bar magnets can be offered in other dimensions and grades. We supply custom made alnico magnets. You can have other colours as well if you wanted e.g. black.
Alnico cylindrical bar magnets are high-performance permanent magnets crafted from Alnico (aluminium-nickel-cobalt) alloy, known for its excellent temperature stability, resistance to demagnetisation, and long-lasting magnetic strength. These magnets are designed in a cylindrical bar shape, providing a consistent magnetic field around the magnet’s surface, making them ideal for a wide range of industrial, workshop, educational, and everyday magnetic applications.
The smooth, round profile of Alnico cylindrical bar magnets ensures uniform magnetic attraction and reliable performance when used for holding, positioning, or magnetic interaction with ferrous materials. Their robust construction and dependable magnetic properties make them suitable for both static and dynamic applications where stable magnetic contact is needed.
Alnico magnet material maintains strong magnetic performance even at elevated temperatures, outperforming many other permanent magnet types in thermal environments. This makes Alnico cylindrical bar magnets a practical choice for fixtures, tools, magnetic assemblies, test jigs, teaching aids, and general magnetic holding solutions.
