Disc Magnets
Discover our range of samarium cobalt (SmCo) disc magnets, a strong permanent magnet often used in automotive and industrial manufacturing applications. Samarium cobalt is what’s known as a rare-earth magnet, which is a permanent magnet made from alloys of rare-earth elements – in this case, samarium. These types of magnets only lose minute amounts of magnetism over time, making them essential in a huge range of industries. Samarium Cobalt Disc Magnets are used in the Design & Manufacturing of Weather Station Equipment. Also valve monitoring equipment, precision and concept to design engineering. High temperature resistance.

Samarium Cobalt (SmCo) Disc magnets
Samarium cobalt (SmCo) is a type of rare earth magnet that has the ability to operate in high temperatures and has superior resistance to corrosion. 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. SmCo is the alternative to Neodymium magnets when a more stable output over a much wider temperature range is required. The SmCo magnets can be used from temperatures nearly as low as absolute zero (-273°C) up to +350°C. Although Neodymium magnets provide stronger fields at room temperature, SmCo starts to outperform at temperatures above +150°C. With superior temperature coefficients than Neodymium, magnetic output from SmCo varies less over a change in temperature, making it an ideal choice for temperature sensitive applications such as sensors and loudspeakers where stability of the field during operation is important. SmCo also has a very good intrinsic coercivity allowing it to be used in applications where high external demagnetising forces (and high temperatures) may be present, such as the starting of an electric motor. SmCo has very little free iron in its structure meaning it offers excellent corrosion resistance to water. It very rarely requires protective coating (e.g. a nickel coating to allow soldering to a printed circuit board). Because of its performance characteristics SmCo is often used instead of Neodymium in mission critical applications such as aerospace and military applications.
SMCO DISC MAGNETS
Samarium cobalt (SmCo) disc magnets are made of an alloy of samarium and cobalt. They have strong magnetic strength like as neodymium disc magnets.The reason why SmCo disc magnets are widely used is their ability to maintain magnetic force. For example, SmCo disc magnets can work in applications that operate at extremely high or low temperatures.
If you need rare earth disc magnets that are not easily corroded or oxidized, then samarium-cobalt (SmCo) magnets will be available. Protective coating is usaually not needed for SmCo disc magnets. However, we recommend that you use them with care because they are fragile and easy to crack or chip.
