Pot magnets are made up of magnets (NdFeB, SmCo, AlNiCo or Hard Ferrite) and other spare parts, such as metal, plastic, rubber and other components. Sometimes Potmagnets can meet some special requirements while a single magnet can not do. Inthe meantime, using pot magnets can save more cost than just using magnets andgain the same purpose.Ceramic pot magnets are powerful magnetic assemblies which are available in various dimensions and diameters. These magnets have wide applications and are applicable at temperatures of up to 200°C. These pot magnets are encased in a non-magnetic cup and are ideal for holding and fixing applications.
Ceramic magnets have structural advantages as they have limited interior dimensions.
They can be housed in a steel pot due to which the magnetic field can be screened off.
The ceramic magnets can be easily fastened that is they can be pressed, glued or screwed.
Heating of ceramic magnets decrease the magnetic force by 30% to 40%. However the magnetic force is restored to the normal ambient temperatures.

Alnico magnets are strong and permanent. They are made of aluminum nickel and cobalt and work under normal conditions and temperatures. They come with removable keepers. This pot type alnico magnet is 8 oz., is 13/16" in diameter and has a 10 lb pull. It has a 1/4 x 20 TPI center hole for attachment. Alnico pot magnets are strong permanent magnets with great temperature resistance and are applicable up to a temperature of 450oc. Normally they are housed in a steel pot having non-magnetized materials like brass or aluminium in between. The magnetic force get reduced at high temperature however it is restored as the pot magnets get cooled in room temperature. The alnico pot magnets are available in different sizes and shapes. These magnets are primarily for gripping applications. The outer surface of the magnets can be either painted or coated with Zinc, Nickel or Chrome.
