what's magnet(SmCo, NdFeB) discs? where's neodymium cylinder magnets manufacturer? how to buy samarium cobalt disks magnets?

Neodymium disc magnets are great for almost any magnet application! These high performance magnets can be easily fixed into position and are commonly found in point of sale display units, stationary folders, scale models and industrial applications.

Samarium Cobalt (SmCo) disc magnet is the other Rare Earth magnet! 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 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 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. Because of its performance characteristics SmCo is often used instead of Neodymium in mission critical applications such as aerospace and military applications.

SmCo is a brittle material and could break, chip, snap or possibly even shatter if mishandled. Care should be taken when assembling with the SmCo .
