Alnico magnets are classic permanent magnets known for their stability, reliability, and excellent performance in applications where temperature and environmental conditions vary. Made from a blend of aluminium (Al), nickel (Ni), and cobalt (Co), Alnico magnets have stood the test of time as dependable magnetic solutions in industrial, scientific, and educational settings.

At Jobmaster Magnets, our range of Alnico magnets offers consistent magnetic strength and durability across multiple product types. These magnets are widely used in instrumentation, motor assemblies, sensors, magnetic fixtures, measurement tools, and specialised applications where long-term magnetic stability is essential.

Alnico magnets are particularly valued for their temperature stability and resistance to demagnetisation. Unlike many modern rare earth magnets, Alnico types maintain performance in high temperatures and are less prone to magnetic degradation over time. This makes them ideal for environments where thermal exposure or fluctuating conditions are a regular challenge.

Explore our selection of versatile magnet formats designed to suit different use cases, from compact, general-purpose Button Magnets to heavy-duty Pot Magnets and precision Round Bar Magnets, all built with quality materials and engineered for professional use.

What is an Alnico Magnet?

An Alnico magnet is a type of permanent magnet composed primarily of aluminium, nickel, and cobalt, often with small amounts of other elements to improve performance. These magnets are made by casting or sintering the alloy and then magnetising it to produce a stable magnetic field. Alnico magnets excel in applications requiring thermal resistance and long-term magnetic reliability, even if their overall strength is lower than modern rare earth magnets.
