Due to its excellent performance, pot magnets have a wide range of applications in industry and our daily life. If you want to know the types of pot magnets, then you have come to the right place. In this article, we will briefly introduce the types of pot magnets. But before we continue, let's figure out what a pot magnet is.

What are the pot magnet material components?

Ferrite, Alnico, NdFeB and SmCo-SariumCo materials are all commonly used in pot magnets. Each type has its own properties and characteristics. Size wise, the NdFeB version will be the most powerful and the ferrite version will be cheaper but the least powerful (size wise). The SmCo version will not be far behind the NdFeB in terms of performance, but with better temperature characteristics. The Alnico version will have a range of properties depending on its design, but is better suited for higher temperature applications. Read more about magnet materials

What is the temperature resistance of pot magnets?

A typical pot magnet can provide pulling forces from less than 1 kg to as high as 130 kg (possibly higher). Most pot magnets can operate at temperatures up to +80 degrees Celsius (up to 60 degrees Celsius for rubber coated versions). At higher temperatures, magnet materials become limiting (standard NdFeB materials are limited to +80 degrees Celsius, but higher temperature grades can be used) or production methods may become limiting (e.g. adhesive temperature limits or coefficient of expansion that causes problems). 

As a result, some Alnico pot magnets may be rated at 220 degrees Celsius (even though Alnico may work fine at 450-550 degrees Celsius) because the pot magnet is designed to expand the material at a different rate, causing the assembly to risk loosening at temperatures above that. However, to solve this problem, we produce special pot magnets that can operate at temperatures up to 450-550 degrees Celsius (e.g. for high temperature applications such as welding). We offer magnetic solutions for a wide range of applications and can take environmental conditions into account.

What are the shapes of pot magnets in the market?

With hook or eyebolt, countersunk (for screws), through-hole (for bolts and cap-head screws), male and female threads (for attaching nuts or entering threads), blind end (for press-fit), etc.

They may have variants of their names, which usually describe how they work or their shape/style, e.g. Capshell pots, which use threaded hooks to help pry the magnet away from the clamping surface, shallow pots that are very thick, deep pots that are tall, bipolar pots.
