Alnico Magnets Typical Physical Properties

Typical Physical Properties for Alnico Magnets

NB: Ranges are indicative for product category, please check individual products for specific values within that range.

This table outlines the typical physical properties of Alnico magnets. This is a general overview however if you are looking for information on a particular product we recommend reviewing the individual product page. Here at AMF we put a great deal of care into updating our website with the most accurate and up to date information.

We know buying magnets online can be daunting especially for those without extensive knowledge of magnetics. In addition to the individual product pages there are also category pages and FAQ articles that hold helpful information. If you have any questions you are always welcome to contact our sales team via phone or email.

Alnico magnets were first discovered in the 1930s and were a revolution at the time. Alnico magnets are composed of an alloy of Aluminium (Al), nickel (Ni), and cobalt (Co), hence their name being an acronym; Al-Ni-Co. Alnico magnets may also include copper and occasionally titanium.

Alnico magnets are significantly weaker in magnetic power than Neodymium magnets. However they remain popular for a number of applications. The metal alloy composition of an Alnico magnet has resulted in a material that is resistant to both high temperature and corrosion. Alnico magnets are available in a number of shapes and sizes. Cylinder magnets, block magnets and horseshoe magnets are all part of the Alnico range. As are pot magnets which are fitted with a metal cap that provides an easy means of attaching the magnet to non ferrous materials.
