Ceramic Magnets

Sintered Ferrite Magnets

Sintered Ferrite (Hard ferrite magnets) were developed in the 1960’s as a low cost alternative to metallic magnets. Even though they exhibit low energy (compared with other permanent magnet materials) and are relatively brittle and hard, Ceramic Magnets (Hard ferrite magnets) have won wide acceptance due to their good resistance to demagnetization, excellent corrosion resistance and low price per pound. In fact, measured by weight, ferrite represents more than 75 percent of the world magnet consumption. It is the first choice for most types of DC motors, magnetic separators, magnetic resonance imaging and automotive sensors.

Besides industrial application, Ceramic Magnets (Hard ferrite magnets) are widely use in Educational area.

SmCo Magnets

Samarium Cobalt MAGNETS

Permanent Samarium Cobalt magnets (SmCo) are composed of samarium, cobalt and iron.
These rare earth magnets are extremely strong for their small size, metallic
in appearance and found in simple shapes such as rings, blocks and discs.

Attributes of Samarium Cobalt

  • High resistance to demagnetization
  • High energy (magnetic strength is strong for its size)
  • Good temperature stability
  • Expensive material (cobalt is market price sensitive)

Applications of Samarium Cobalt

Computer disc drives, sensors, traveling wave tubes, linear actuators,
satellite systems, motors where temporary stability is vital.

Magnetizing and Handling

Samarium Cobalt magnets are very brittle and very strong magnetically. Therefore,
it is crucial to handle these magnets with extreme care to avoid personal
injury and damage to the magnets. Fingers can be severely pinched between
attracting magnets. Magnets can chip if allowed to “jump at” an
attracting object. It is highly recommended that when constructing rare
earth magnetic assemblies, they be magnetized after assembly.

Samarium Cobalt Machining

Since Samarium Cobalt magnet material is prone to chipping and cracking,
it does not lend itself to conventional machining methods. It can, however,
be abrasively ground, but only with the use of liberal amounts of coolant.
The coolant minimizes heat fracturing and the risk of fires caused by
oxidized grinding dust.

Hook Pot Magnets

Pot Magnets (Mounting Magnets) are often used as tools for various activities in workshops and in industry. They can be used for holding workpieces whilst welding, cutting, milling or drilling etc. Because of the lack of moving parts and the robust construction of pot magnets, the life is unlimited and no maintenance is required. Just keeping the pole surface clean guarantee reliable operation and a long life.

How to choose a pot magnet?
The basic principle of the holding or pot magnet is to direct and concentrate the flux from both magnetic poles to one active face. This is usually achieved with steel pole pieces or a steel-backing cup.

The standard selection can be broken down into three material types and there is a great variety of systems available. The following data should act as a simple guide:

1) Rare Earth Samarium & Neodymium, pots and assemblies can offer up to eleven times the performance of a Ferrite system in a comparable size. Applications tend to be specialized engineering projects where performance and available space are key factors. Maximum operating temperatures are +60°C for the Neodymium and +150°C – +250°C for the Samarium depending on the design configuration.

2) Sintered Ferrite, this material offers a good performance from an inexpensive magnet, however, they tend to be bulky and are not always suitable where space is an important factor. The steel parts are plated & the Ferrite is inert thus corrosion is limited. Maximum operating temperature is +120 °C.

3) Cast AlNiCo, offers a better holding force than Ferrite systems and is the only pot magnet that can be heated to extreme temperatures. However, the high cost of the Cobalt content in the cast magnet makes the price prohibitive unless the application requires temperatures over +120°C up to a maximum of +500°C.

When considering your selection, please be aware of the following factors: The stated Kg Pull (holding/gripping force) is based on the magnets retaining force against a direct pull when offered to a clean ground mild steel surface with a minimum thickness of 8mm. Painted or un-ground surfaces will reduce this force, assemblies working in shear will support approximately 1/3 of the stated value.
