Block Magnets
Samarium Cobalt (SmCo) Block Rectangular Magnets have a variety of applications, including motors, generators, aerospace and manufacturing industries, as well as experimental research and engineering. Many of these applications depend on samarium cobalt magnets due to their large temperature range – from just above absolute zero (-273⁰C) up to 350⁰C. Care should be taken when assembling with SmCo due to its brittle nature (e.g. wear safety glasses). SmCo could break, chip, snap or possibly even shatter if mishandled.
Samarium Cobalt (SmCo) Block 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 BLOCK RECTANGULAR MAGNETS
Samarium cobalt (SmCo) block magnets are also known as rare earth block magnets and are made of an alloy of samarium and cobalt, which also have strong magnetic force like as neodymium block magnets. Because of their ability to maintain magnetic force, samarium cobalt (SmCo) block magnets are a better choice than neodymium block magnets for working in extremely high temperatures. The SmCo magnet blocks that have equal sizes for length, width and thickness are called SmCo cube magnets.
If you need rust resistant rare earth block magnets, then samarium-cobalt (SmCo) magnets, Magnosphere will be your first choice. Surface treatment is not needed for SmCo block magnets. However, they are fragile and easy to crack or chip, we recommend that you use them with care.
ROHS-Directive
Magnosphere conforms to the RoHs directive and the Reach and PFOS regulations. Directive 2002/96 / EC of the European Parliament and of the Council, of January 27, 2003, on waste electrical and electronic equipment (WEEE).
