Product Description

SmCo Countersunk Pot Magnets, Samarium Cobalt Countersunk Pot Magnets, SmCo Pot Magnets with Countersunk Borehole / 90 ° Countersunk (Countersink) Hole

SmCo Countersunk Pot Magnets – High power ‘rare earth’ magnet material. Slightly less powerful than neodymium but works up to 200 °C. (Neodymium is usually only usable up to 120°C.)

Use where:
High power is required from a smaller magnet
Components and materials have to be held – jigs, assembly fixtures and positioning
Temperature is lower than 200 °C
Sintered SmCo magnet is one of the two types of rare earth magnet, which is made of an alloy of samarium and cobalt. It is the second strongest powerful of magnet, but has better temperature stability (maximum working temperature is between 250 and 350 °C and the curie temperatures is from 700 to 800 °C). The flux density of sintered SmCo magnets will vary under 5% per 100°C change in temperature (in the range of 25–250°C). They are mainly used in the high-end applications which require operating at cryogenic or high temperatures (over 180°C), such as electric motors, turbo-machinery and traveling-wave tube.

Similarly to many other rare earth magnets samarium cobalt is brittle and can be chipped and cracked easily making them unsuitable for applications that require repetitive direct impact to the surface of the magnet. These magnets are often best used in applications where the magnet is recessed into a hole or groove to protect the magnet from impact. This high performance, high temperature magnet is typically found in food and industrial manufacturing industries.
